I've had a look through the logs you sent, but I don't see anything obvious problem. The following lines in one of the logs are not good: (WW) I810(0): PRB0_CTL (0x000b6007) indicates ring buffer enabled (WW) I810(0): PRB0_HEAD (0x008b662c) and PRB0_TAIL (0x00092660) indicate ring buffer not flushed but they don't appear in the second set of logs. The only other thing I can think of right now is to trace through which call to VBESetVBEMode is made, and print the parameters in each case, and call I830_dump_registers() before the VBESetVBEMode() calls. You'll need to build with I830DEBUG defined (uncomment it in i830.h).
