Hi everyone:

I may have found it.  There is a note on page 240 of the ICH5 datasheet
that says:

	For I2C Read command, the value written into bit 0 of the
	Transmit Slave Address Register (SMB I/O register, offset
	04h) needs to be 0.

We're writing a 1 (as would be expected: it's a read after all).  I'll
test this hypothesis tomorrow evening... right now I need sleep.

Regards,
