It is exactly the same issue. Bug 949288 requests that radeon FB be built into the kernel.

The presence of FB_radeon will stop KMS from working (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/59651 ) so you will still have suspend.

Without KMS you won't have 3d hardware acceleration though (see https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/946677 ). Some applications also now require KMS so the option to easily enable KMS is beneficial.

The current setup of 11.04, 11.10 and 12.04 neither benefits radeon UMS or KMS. Bug 949288 tries to find a setup that works for UMS and KMS, and it does. You can alter your graphics setup from the kernel command line (yaboot prompt) unlike at present which requires altering several files.

BTW, compiling a kernel is an extreme solution to your suspend problem. See https://wiki.ubuntu.com/PowerPCFAQ#Power_preferences.2BAC8-suspend.2BAC8-multimedia_keys .
