Fedora Core 2 installs and runs fine with no extra intervention, with the exeption of the modem, which is a Xircom 'winmodem' - see linmodems.org for enlightenment.
'apmd' doesn't function properly (due, I believe, to a non standard BIOS), however suspending via the keyboard and closing the lid works fine. Resyncing the system clock with 'hwclock -s' is recommended when the system wakes, as is restarting networking and PCMCIA services.
APM battery monitoring works.
No ACPI support.
Good:
Fantastic keyboard and bullet-proof construction. I can get 2.5 hours from a two year old battery on the 500Mhz PIII.
Bad:
Screen viewing angle is quite limited, so corners can seem dark. Relatively heavy (it was designed as a desktop replacement).

NB:
Running lm_sensors' sensors-detect is said to destroy data on the EEPROM on some Thinkpad models. I don't know if this is one of them, and I'm not willing to find out the hard way. I would advise against it anyway.
