1. I found a bug in the driver source. I was looking how I can  
disable this int10 stuff. There were some ifdef's around that read:

#if defined(__powerpc__) || defined(__alpha__)

and a comment that int10 is not working on alpha.

Bit one ifdef was only:

#if 1 && !defined(__alpha__)

I changed that to

#if 1 && !defined(__alpha__) && !defined(__powerpc__)

Now it does not try to load int10 module. But now comes another error:

(II) R128(0): PCI bus 0 card 16 func 0
(==) R128(0): Depth 24, (--) framebuffer bpp 32
(II) R128(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp pixmaps)

(==) R128(0): RGB weight 888

(--) R128(0): Chipset: "ATI Rage 128 Pro ULTRA TR (AGP)" (ChipID =  
0x5452)
(--) R128(0): Linear framebuffer at 0x08000000
(EE) R128(0): No valid MMIO address


Looks like it has to read some information from the chipset, either  
via framebuffer or via int10. Both is not available on PPC BSD.

Looks like the Rage only works with Linux. ???
