I also tried your "DRIReinit" option of radeon driver but even if I switch to a text console and I unload both agpgart and radeon before suspension from time to time during resume it reboots automatically (the same behaviour occurs if agpgart is loaded during resume but in this case it happens all the times), have you any suggestion?
The ati agpgart module needs PM code. Take a look at the the i845 patch here for details: http://cpbotha.net/dri_resume.html I think you just need to call the module init/configure function again on resume. I'm not sure any of the vanilla agpgart modules have support for resume at the moment.
I experimented (no data sheets) a bit with sis on 2.6.
Lost HW state is one obvious issue which a) Causes lack of functionality b) MCE's on some HW.
I added suspend/resume (both!) functionality on the HW side but this had no effect whatsoever.
Kernel still crashes well before resuming drivers which would do as you suggest.
Also disabled Resume - still no difference.
Then I tok out selective pieces of code and found that crash seems to be related to the AGP frontent (user side) rather than backend (HW).
So, there seem to be issues outside of AGP (HW)...
Will take a bit more time to research.
My gut tells it is "where nobody ever looked" - as usual ;)
