So I figured, thanks for making it clear.

Sounds ideal if one init procedure can cover both chip revs.

I'm keen on taking a Rev.B1 chip for a spin, so I'll jump on doing doing
the init/fixup. I can probably post it to the mailing list during the
weekend.
If you're planning on being faster than that I'll wait for your
submission.

Out of curiosity do you have any insight into if the rev b1 is expected
to behave differently?
