Tak,

I just wanted to make sure you knew of the different types of sbxfi
cards.

For instance, I have this one:
http://www.geeks.com/details.asp?invtid=SB0670-BULK&cat=SND

It's still emu20k1.  However, it is impossible to use with creative's
drivers, as it always causes a lockup, but it works with oss4 drivers.

I don't know if this matters to you at all, but I wanted to let you know
in case it affected how the driver progressed to be compatible with the
most emu20k1 cards.
