I had a play with this since I also see poor quality with my 761 card, 
trying cpump values of 1, 2 and 3 for the 470..750Mhz range with your 
patch to also do cpump << 6.

I ran tzap for 60 seconds on a mux at 665Mhz and recorded all the ber 
values, extracted into a spreadsheet:

cpump	1	2	3
average	13804	6071	5365
median	9618	5494	4758

which is still not exactly great but it seems cpump=3 gives the best 
results; I'll do some more testing with this patched driver and report 
back later in the week.  If there's anything else it would be useful to 
test let me know.
