Hi

If you sign off your patches they can be reviewed, acked, and committed.
Done !
You could try having SeaBIOS enable your ROM. There have been several cases where SeaBIOS was less picky than the others.
I forgot to mention that also tried seabios without success.
If you send me a log from before and after the patch it'll help both of us :)
I'll try this patch and report my results.
