Hardware

Configuration will vary. Spec for 0768-36U model:

Intel Celeron Duo T2300 @ 1.66GHz / Core Duo / Core2 Duo T5500 (or T7200)
Intel Mobile 945GM/GMS/940GML Express Video / NVidia Geforce 7300
Intel High Definition Audio AD1986A
Intel USB UCHI (x4)
Intel USB EHCI
Intel 82801GBM/GHM (ICH7) SATA storage 
Intel PRO/Wireless 3945 ABG wifi
RealTek RTL-8139/8139C/8139C+ wired
ENE Tech CB1410 Cardbus
Ricoh (unknown) Firewire
Ricoh MMC/SD adaptor
Ricoh (unknown) something
Ricoh Memory Stick adaptor 
Ricoh xD-Picture Card
Broadcom USB Bluetooth (internal)
ATA hard drive
PATA cdrom drive
AuthenTec AES2501 Fingerprint Reader
Microdia Webcam

On models with the Core 2 Duo T7200+, Intel VT virtualization extensions are disabled by the BIOS with no option to enable them, even after upgrading the BIOS (as of Ver. 2.06 (61ET37WW), 2007-06-28).

The Ricoh devices are actually a single chip, which reports itself as 5 PCI devices. Four of these are pretending to be other Ricoh single-function PCI chips: the firewire, the MMC/SD, the Memory Stick adaptor, and the xD-picture card. The fifth one is the multi-function chip's own PCI ID, which doesn't do anything other than let you know what multi-function chip you actually have.

Kernel Config and Working hardware

Works with sys-kernel/gentoo-sources-2.6.17-r8:

Troubleshooting

Buzzing sound from the battery

Add max-cstate=c2 to the bootloader's kernel parameters.

Stuck num-lock and disabled touchpad when waking from sleep

Add i8042.nomux to the bootloader's kernel parameters. On some machines (at least model 076831G) the system may suddenly hang when using touchpad, even after several hours of uptime. No error is found in syslog. To resolve this issue replace i8042.nomux with i8042.reset option. This is valid for kernels starting with version 2.6.18.

black screen with backlight switched off after a wake up from a suspend to ram

Try to boot with the acpi_sleep=s3_bios kernel parameter.

Internal Speakers not disabled when external speakers connected

With ALSA 1.0.15, you need to have the model end up as "laptop-automute", but there's still an issue that you need the last patch from the above bug because Lenovo's sense bit is inverted from what the driver expects.

sound card is not detected at boot time

"Internal Modem" has to be enabled in BIOS. The modem and sound card are handled by the same chip.

Note: Sound is reported not to work at all on some models.

Wireless Networking Problems

Graphics Card

Intel GMA 950

See this HowTo.

NVIDIA Geforce 7300

emerge x11-drivers/nvidia-drivers is sufficient. Don't forget to run eselect opengl set nvidia.

Restoring the video after suspending requires vbetool post, and vbetool vbestate restore seems to cause it not to work. I haven't found a way to make hibernate do the POST but not do the restore state, so I haven't determined if that works inside the script. After vbetool post, the backlight goes on, but the screen is blank until you do something to cause the kernel to redraw the screen (I think because the POST takes long enough that the kernel has redrawn everything directly due to the command before it completes).
