I'm using Fit-PC1 units (fit-pc.com) as web development pre-prod. One of these requires X installed.
Although it is not listed as supported OS, I go with my preference and run Debian instead of recommended Gentoo or Ubuntu.
Install worked fine with Lenny but on Squeeze, the graphic card is not setup up correctly anymore.

reassign 637778 xserver-xorg-video-geode 2.11.9-7
kthxbye
Looks like the X server crashes when the geode driver tries to get the
modes, reassigning to the driver.

Cheers,

Thank you for re-assigning this bug. That assessment is correct. This
being said, we did not know of any commercial product that ships with
the DDC pins configured for serial I/O but, apparently, this one does
and sadly our driver doesn't know how to fall back to some usable mode
or how to bang the GPIO bits back into DDC state before probing. I
guess that this something we'll have to get around implementing now.

Correction: Actually, install does not work neither on any version of
Debian nor on Ubuntu, which I've tested on these devices using every
version since 8.04, without any luck (bug reports for Ubuntu have been
commited to Launchpad bug tracker). On Ubuntu and on Debian, versions
prior to Squeeze, it was possible to run graphics in safe mode and get
a desktop; also it was possible to concoct some settings in xorg.conf
to make things work...but not anymore.
One question remains: Is it worth the effort if only to satisfy users
of Fit-PC 1, which are no longer in production? Compulab will release
a version 3 of the device in fall this year ( see
http://www.fit-pc.com/fit-pc3/ ).

Dávur,

I'm curious whether the Fit-PC 1 has a BIOS setting to flip the GPIO
back into DDC mode. Could you check this? If not, it might be worth
placing a support ticket with FIT to produce a corrected BIOS, since
putting the DDC pins into serial console mode has very few uses in a
production environment.

Dávur,

Does the issue still apply to recent versions of the driver on Debian?
