-current with radeondrm fails on HP DL360 G5 and DL320 G6


 I tested today's -current on HP DL360 G5 and DL320 G6. This machines
have the same video chip:

001:03:0: ATI Technologies ES1000 (VGA display, revision 0x02)

And, while attaching radeondrm, it stopped with black screen.

The console output is like this:

> drm: Initializing kernel modesetting (RV100 0x1002:0x515E 0x103C:0x31FB)

 For amd64, the screen becomes black. For i386, it continues as follows:

> drm: radeon: ring at 0x00000000D0001000
> DRM error in r100_ring_test: radeon: ring test failed (scratch(0x15E4)=0xCAFEDEAD)
> DRM error in r100_cp_init: radeon: cp isn't working (-22)
> radeon: error: failed initializing CP (-22)
> radeon: error: Disabling GPU acceleration

and then the screen becomes black.

I commented out the following two lines from GENERIC and the
kernel booted fine:

> radeon*         at pci? dev ? function ?
> radeondrmkmsfb* at radeonfbbus?
