[Bug 352050] Re: [HD3650] fails with mobility hd3650 on startup if > 2GB RAM

[Krelis]

Thanks. I tried the enable_mtrr_cleanup line earlier and added the
mtrr_spare_reg_nr=0 later (in menu.lst), it didn't make the driver work.

After reading this:
http://lists.opensuse.org/radeonhd/2009-05/msg00070.html

and this:
https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.24/+bug/224404/comments/42

,I tried compiling a custom kernel with options "CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1" and "CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=0". This made no difference. I didn't notice any changes in Xorg.0.log besides the added line:
"(II) RADEONHD(0): Current Engine Clock: 13823570", which (i assume) just came from using the most recent (20090519) driver from your PPA.

I'm aware that this is not a radeonhd issue, so i'll keep checking bug
341681 here on launchpad, and bug 20645 on bugs.freedesktop.org. This
post is intended to describe some things that didn't work.

some (perhaps) relevant output below:
