Hmm. I'm not sure what's going on here.

Take a look at /var/log/dmesg and see what comes immediately after those
lines.

You could try with a different graphics card (although I'd have thought
that unlikely).

I'm not convinced that Fedora is picking up all the PCI devices in this
machine. HP documentation
(http://h18000.www1.hp.com/products/servers/ProLiant2500/overview.html)
and a Web search
( http://www.linux-nantes.fr.eu.org/wikini/wakka.php?wiki=LocaL : you
may not speak French, but you should be able to spot the lspci output
under "Passerelle Internet/ Retroviseur") suggest that you should be
seeing at least a "Host bridge" and an "EISA bridge". [1] Do you think
you're seeing everything you should be seeing on this machine?

Is the VGA adapter built-in, or can you move it to a different PCI slot?

Sorry I can't help more.

James.

[1] Hooray! *I* don't have to deal with EISA any more!
