(side note your logs obviously use different configuration - not that it 
matters in this case.)

Both those xf86DrvMsg around there look a bit bogus to me...

That's ok. I think the problem is that RADEONPreInitVRAM misses a return 
value. I'm not sure what the results of that exactly are as it works for 
me, but I'd guess it's undefined which might cause the server to abort, 
in case the result is non-zero. (Wondering why I don't get any compiler 
warning...)

Which is exatly what's happening here.

Some other unrelated remark, I think that the ChipFamily detect for 
setting HDP_APER_CNTL is wrong, it should probably include at least 
CHIP_FAMILY_RV410 too (which is newer than either R420 and RV380). Not 
sure about igps (rs400 is definitely a lot newer), maybe it doesn't 
matter for them.
