  I just want to confirm that the patches you have submitted are working for me
under Fedora 15 64 bit.  Thank you very much for attacking this issue;  my music
sounds great so far with this driver in conjunction with the Titanium HD card. 
Please let me know if you would like me to test any additional changes you may
make with any future patches.
  Thanks again.
