X1300 Mobility Radeon (0x7149) QE/CI not working

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install an OSX86 distro like iDeneb 1.4
2. Add 7149 model support into ATIRadeonX1000.kext
3. Install RadeonHD.kext

What is the expected output? What do you see instead?
- When using only ATIRadeonX1000.kext, QE/CI works fine, but no 
framebuffer is usable as ATY_Caretta + Natit.kext only work for external 
display, so I cannot change resolution on my internal display
- When using only RadeonHD.kext, framebuffer and resolution change work 
fine, but there's no QE/CI support
- Any combination to use both ATIRadeonX1300.kext and RadeonHD.kext ends 
with kernel panic (thread is logged as kextd-related, so possibly some 
conflict between these two kexts)

What version of the product are you using? On what operating system?
RadeonHD.kext 1.0.0d1 from http://www.pcbeta.com/viewthread-667731.html

Please provide any additional information below.

Thread should be probably named "X1300 Mobility Radeon (0x7149) Conflict with 
ATIRadeonX1000.kext" :/

The same thing with 10.5.8.

Have Iatkos v7 install (voodoo 9.7.0 kernel)+ Apple regular update on AMD 
Turion 64 
x2 with x1300 Radeon Mobility. Works fine with only ATIRadeonX1000.kext, 
however no 
res change (1024 only) and some mouse tearing.

While using RadeonHD.kext with auto-EDID sometimes all works flawlessly - got 
full 
resolution and no mouse tearing - a dream. However, sometimes it hangs on last 
boot 
sequence or falls to KP just after booting end. Last string is: 
"IOKitWaitQuiet() 
timed out waiting to write kernel symbols"

Safe mode boot goes flawlessly. Tried:

1. deleted AppleHWSensor.kext
2. EDID hardcoded to RadeonHD.kext
3. kernel updated to 9.8.0

nothing works. The only way to boot successfully with both kexts is to press 
some 
keys on keyboard (shift, space, enter) randomly, to move & click USB mouse 
randomly. 
Almost in all cases this strange passes help to boot successfully.

This ticket can be closed, works perfect for me with 2010 build on 10.5.8.
