Well, today I wish I could get at SDA/SCL - because I think I would have a
working solution to my need (to read the TDA7433).

Maybe it's complex - or at least tedious - because of working within the OS
- but it is also specified by the i2c spec - so a solvable problem.

All the time on this patch has been spent second-guessing what the CUDA does
with its command packets... and at the end I still can't read the chip (lots
of info from the SPDs & other devices ;-)

CUDA is also on m68k? (I see some conditionals in the 2.4.0 stuff for
CONFIG_MAC)

I really would be very grateful if anyone has any more sources of info on
the command packets contents for it (CUDA)...

Iain.
