[ For l-k, the issue is that pci-pci bridges and the devices behind
them are not initialized properly. There are a number of Alphas
whose built-in scsi controlers are behind such a bridge preventing
these machines from booting at all. Ivan provided an initial
patch to solve this issue. ]
I've not gotten a chance to try this on the rawhide yet,
but I did give it a whirl on my up1000, which does have
an agp bridge that acts like a pci bridge.
Notable changes from your patch:
* Use kmalloc, not vmalloc. (ouch!)
* Replace cropped found_vga detection code.
* Handle bridges with empty I/O (or MEM) ranges.
* Collect the proper width of the bus range.
