DRI on FreeBSD with a PCIe X800

[Adam K Kirchhoff]

So I thought I might try and debug this problem further...

I was looking at the various options in the radeon man page and came 
across the BusType option.  I had tried both leaving that option out, 
and setting the option to "PCIE".  This morning, I decided to try 
setting it to "PCI" though, according to the man page, "PCIE" simply 
falls back to PCI at the present time, so I figured it wouldn't make a 
difference...  Except that it does make a difference.  If I set the 
BusType to "PCI" dmesg shows:

info: [drm] Initialized radeon 1.25.0 20060524
info: [drm] Setting GART location based on new memory map
error: [drm:pid1311:radeon_do_init_cp] *ERROR* Cannot use PCI Express 
without GART in FB memory

The only thing different that shows up in the Xorg log file is:

(WW) RADEON(0): Direct rendering disabled

This is after all the usual DRI setup including the opening of the 
/dev/dri/card0 device.

I'm not sure if this is at all related to the problem I'm seeing when I 
use BusType "PCIE" and get the screen corruption...  However, at the 
very least it shows that BusType "PCIE" does not, in fact, fall back to 
"PCI" and something is being setup differently.

If anyone wants to look at the full Xorg from the "PCI" session, it's 
available at:

Dmesg:

If anyone has any tips or pointers on debugging either of these problems 
further, I'm all ears :-)
