I thought i put a little readme in the archive. The idea here is
to set SF_ADDR env variable to your mmio address (get it
using lspci for example if you got:
01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon
X600 (PCIE)] (prog-if 00 [VGA])
Subsystem: ATI Technologies Inc Unknown device 0f02
Flags: bus master, fast devsel, latency 0, IRQ 169
Memory at f0000000 (64-bit, prefetchable) [size=128M]
Memory at fe9e0000 (64-bit, non-prefetchable) [size=64K]
I/O ports at dc00 [size=256]
Expansion ROM at fea00000 [disabled] [size=128K]
Capabilities: <access denied>
$export SF_ADDR=0xfe9e0000
then
$LD_PRELOAD=/pathto/libsegfault.so Xorg > dump 2>&1
with xorg.conf configured to use fglrx driver.
For the video bios spying tools:

I found a couple of things but i am not familiar enought with modesetting,
so i am taking time to understand all this. We may need to start somethings
similar to nouveau to bring more attention and more people on this. I fear
that most current dri dev can't work on this due to NDA or lack of time.
