My IBM Thinkpad R40e works, sort of.

To boot, I had to use this:
Code:
knoppix26 nodma noapic acpi=off
DMA causes it to not see the CDROM. APIC and ACPI make it lock during hardware detection.

Ethernet works with the 2.6 tg3 driver, but not the 2.4 driver.

Sound worked on boot.

Graphics are unaccelerated, I think (glxgears gives 225 fps).

Yeah. I can't test the other stuff, so I'll say this is "sort of working"
