Note that I have not tested it since I don't have the board, but in
theory it should work based on the measurements done by others.

No guarantees from me that it will work - but if you still want to
give it a go we sure would appreciate hearing from you when it's

I think there are some more electronics savvy people reading the
list who could try the mod on their own boards with less effort than
booking a workshop - to confirm that it actually works in practice.
But if you can't wait I completely understand! =)

Yes - make copies of the factory BIOS. Several of them, ideally.

I'd even recommend flashing the factory BIOS into the new chip and
then going back to the shop and replacing one flash chip with a blank
one so you know you have one working flash chip safely stored away
from the board.

I would also recommend using a flashing program separate from the one
in the factory BIOS however, since Q-flash may be making assumptions
about the flash chip contents (since it knows it is stored in flash)
which are no longer true when you flip the switch, and could cause
the flashing to fail.

But it could also just work. :)
