I had linux running on my tp750 (mono). It wasn't easy to get up and
running; I had to patch the kernel in a few places, and use the
UMSDOS hack to actually get a file system on the disk. The main
problem: linux doesn't deal with the 2.88 Mb floppy controller; also
linux uses the disk change signal, which works differently on the
tp750 than on most PCs. (Eventually I got the floppy driver to
actually read/write 1.44 Mb disks, but the disk change line still
didn't work, so if you swapped floppies the old cached data wasn't
invalidated.)

I used the monochrome driver; it worked fine once I figured out the
clock values. I didn't have a color display to try.

No. Actually it's quite annoying. Even the power switch doesn't
work reliably.

That's right. I just duplicated the type 4 entry for the type 5 and
6 slots. But there are other problems as well.
Versions of linux after 0.99pl13 would just get wedged, apparently in
the hard disk driver code.
You can have my patched versions of kernel files by ftp-ing to
cs.utk.edu, directory pub/moore/linux.
I'm currently running netbsd on my thinkpad; it also required
several patches, but works much better than linux did.
