this shouldn't be fatal... i do see it myself, but i'm not sure what
is up.  i won't be able to look at this for a couple of days.

Indeed. The real problem comes from libpciaccess which is not able to
read the video bios for the intel driver ...

37 237         ret = pci_device_read_rom (pI830->PciInfo, bios);

Looking at the code, pci_device_read_rom() is not implemented for
NetBSD :(

static const struct pci_system_methods netbsd_pci_methods = {
       pci_system_netbsd_destroy,
       NULL,
       NULL,                        <--- read_rom()
       pci_device_netbsd_probe,
       pci_device_netbsd_map_range,
       pci_device_netbsd_unmap_range,
       pci_device_netbsd_read,
       pci_device_netbsd_write,
       pci_fill_capabilities_generic
};

Do you have the latest libpciaccess?  0.10.6 (from pkgsrc) shows:

That's the one from xsrc.

static const struct pci_system_methods netbsd_pci_methods = {
       pci_system_netbsd_destroy,
       NULL,
       pci_device_netbsd_read_rom,
...

Ah ... pci_device_netbsd_read_rom() comes from patch-ac.

That said, I cannot get the radeon driver to work.

With the attached patch, X is back with the intel driver.
But i'm pretty sure this will break on non x86 archs.

That reads the legacy VGA ROM and is indeed PC specific. Other archs will have to find its bus address from the ROM BAR, hope it's valid, enable it, map it etc.
Also, OF ROMs on graphics boards tend to be bigger than 64KB.

have fun
Michael
