hmmm... everything else looks pretty good.  Try the attached patch.
Maybe the pll isn't quite right.  You might try diffing the 2 reg
dumps you sent me originally and using them as a guide to identify
which registers are problematic.  Boot up to the broken state and then
use radeonreg to set the registers to the values from the working
dump.  e.g.,
radeonreg regset 0x00000250 0x009f0013

Some of the registers are related the memory configuration of each
driver so try the following registers:
00000050 03000600
00000054 00008048
00000058 ff002102
00000204 008c051b
00000250 009f0013
00000254 03ff0026
00000278 009f03ff
0000027c 00000030
00000284 000300cd
000002c4 008c001e
000002c8 00860004
000002f0 20007c7c
000003f8 02000200
0000088c 07880100
00000d04 00000806
