I just tried booting the 20011111-1.5Y snapshot on my IBM PS/2 9595. I don't
remember the exact revisions of the hardware in it, but I think the planar
is the last from the xx95 series, and the complex is the first pentium-based
one (I think there was a second pentium-based one too).

Booting proved troublesome, saying just "Boot failed". Setting the floppy to
1.44MB mode solved this (and of course caused errors in POST..), which makes
me think the bootloader tried to read the floppy as 2.88MB. (DOS boots fine
from floppy, and IIRC so does linux (using whatever Debian 2.0 used on their
boot-floppy).)

Anyway, I didn't go much further than booting the install-system, since the
SCSI-controller isn't supported. But I can move about in the installation
menus at least. And I'll send dmesg and some comments:

There it is, in all it's unsupported glory.. I have an earlier IBM MCA SCSI
controller somewhere (I last saw it before I moved, but I think I have a
good idea of where it is). Would sending this to someone help driver
development?

I was unable to receive packets on this interface (sending worked though).
(Using the AUI-port, since I don't have a convinient place to put the other
end of a TP-cable.)

This is just the gfx-card, nothing interesting.

I have no idea why it doesn't want to configure my other 3c529.
(This is the BNC-model)

Well, that's it..
