Plug-n-Pray being what it is, my values are different.  The only thing
that really strikes me is your IRQ (mine is IRQ 21).  You should look in /proc/interrupts
and see what else might be sharing with the sound card.

It may simply boil down to drivers.  What modules are you building for
your kernel?  I'm running 2.6.17.6 and lsmos shows the following:
