X server on PCI-based sparc

[cyan051]

this issue affects all xfree v4.x builds and all currently present xorg builds (including xorg r6.8 ).
surprisingly enough, xfree v3.3.6 works just fine (but then, who wants to run X11 R6.3? besides, its incompatible with udev)

basically, if u used kernel 2.6 on pci-based sparc (for exp. ultra 5, or like mine e250, or any new stuff), any x server was unusable - enumeration of /proc/bus/pci was broken.

then in march 2004 came one patch which did make it work on a single-pci bus systems - see bug post:
https://bugs.gentoo.org/show_bug.cgi?id=43630

this patch is included in current x builds (xorg v6.7 and above and xfree 4.3.99 and above, but not xfree 4.3), but it only enumerates /proc/bus/pci/0000*.

so, in case your adapter is on some other bus, it wont be recognized.
to add to confusion, fbdev will find something but forget about native support (in my case, glint driver used for raptor gfx adapter) (also, not like fbdev works like a charm - it more often doesn't)

so, i'm preparing a new patch for this broken source:
