Hiya Folks,

in followup to the TGA thread i'm having difficulty with getting X to 
work/compile on my PCI based DEC PWS 500au machine....

XF3 will compile but it wont start XalphaNetBSD for its prolly for TC's 
only ... or is that TGA a PCI one ? or what ... i am a bit puzzled by this 
TGA thingy...

The machine has an Elsa GLoria Synergy PCI card as shipped ... Its 
supported in XFree86 but i cant get it to work yet...

I know someone (Simon?) was working on trying to get PCI devices to work in
XFree86 for i _had_ a working X server ... I've tried compiling XF4 but it
i get a lot of linking and undefined var's... were the patches lost when XF
4.2 was imported or so?

Attached are the patches that are minimally needed to get a linked but not 
working X server... haven't had the time to further investigate though ...

Hope we can get X up and running before the 1.6 release goes out .. FreeBSD 
and OpenBSD seem to _do_ work :-/ .... NetBSD is way behind on this.

Maybe also a good point is to split off NetBSD stuff from the 
os-support/bsd ? its getting a real #ifdef forrest now that doesnt help 
much at all.
