Hi,

Ever since 2.6.26 or so (where there was a code reorg) I had to carry 
this patch.
Without it the received signal is noisy, and the card worked fine prior 
to the code
reorg. This patch is a hack, mostly as a result of my inability to 
follow the code
paths (and bisect failing). I'd be more than willing to test whatever 
the proper
patch might be prior to any mainlining.

Thanks,
/Anders
