Just to reiterate since everybody seems to forget this part: The problem 
does *not* occur when using a 2.4 kernel. Additionally, I seem to recall 
that when I tried compiling a 2.6 kernel without ALSA support (so OSS is 
native and not emulated), the problem went away even with the 2.6 kernel 
(this was back around 2.6.11ish time), though I may have misremembered that.
