Please try radeonfb just to see if it makes any difference.

Okay. I'll likely be compiling that later today.

I have another idea. Please run pcictl pci0 dump -d <whatever device
number your radeon is on, pcictl pci0 list should tell you> before
starting X, then start X like before, just with an xterm, run the same
command and look for differences in the BARs. If the Xserver feels
like messing with the BARs then whatever console driver we use would
cause a panic immediately when trying to write video memory. I don't
really see evidence of this but who knows.

Okay. I gave this a shot, and the diffs are in the "Common header"
<     0x00: 0x59621002 0x02b00006 0x03000001 0x0000ff08
---
   0x00: 0x59621002 0x02b00007 0x03000001 0x0000ff08
And:
<     Command register: 0x0006
<       I/O space accesses: off
---
   Command register: 0x0007
     I/O space accesses: on

Oh for crying out loud. I/O access: on is the case that works?

Also, I set wscons=YES for this run, and tapping the vt switching key
combo got:
Failed to switch consoles (Inappropriate ioctl for device)

Not surprising if you don't have virtual consoles configured.

And when exiting the xterm, that was followed by: finished PLL2

That comes from the radeon driver.

have fun
Michael
