Yes, that seems to be the case. The patch basically disables and again
enables the bus so that the missing clock pulse gets generated. I also
changes the code a bit so that an extra byte is not sent at the end of
transmissions.
The message http://ozlabs.org/pipermail/linuxppc-embedded/2005-July/019076.html
suggests to use a bit-banging driver instead of the buggy MPC5200 i2c
hardware. Maybe I'll look into that.

Maybe it's indeed time to start using the 2.6 series, then. Thanks!
