motherboards

[Observer <obs...@mo...>]

I found that some motherboards at incompatible with ruby at some degree,
running 2 xservers using the same driver will hang the system, have any
of you have this problem?
I have only some old motherboards where i have get a usable
configuration, but i would like to know about some recent working models
so i can change the one i have, any suggestions?
I think the problem is part xfree and part the bios, the system cant
allocate resources for the cards, when running a "normal" xfree
multihead configuration the server resolves any conflict and it works
fine but running whit SingleCard or IsolateBus the system hangs when the
second copy of the same config is loaded and before any log is written
to disk, I have debugged the server but i havent found the exact line
where it hangs (I think it hangs after the actual error has happened).
I'm attaching the output of dmesg and lspci -v in case someone can help
me out with this.

Thanks.
