Donald, I have about 10 data points now from people who have used the
CSR18 bit 1 patch. For most of them (9 out of 10) it fixed the problem
and for the last it didnt change anything, eg it didnt make things worse.

I sent a couple cards to Jeff Garzik at mandrake and he was able to
duplicate the problem and confirm the fix as well.

I know you cant reproduce the problem but lots of us have the problem and
CSR18 bit 1 really does fix it. Please consider adding it to the driver.
