vorbis RC3 + Potato X11 = complete crash (not even pingable!)

[Seth Delackner]

Anyone else seeing this problem?  If so much as:

        $ ogg123 -d oss foo.ogg &
        $ startx

My entire machine instantly always crashes to the degree that I can't
even ping it.  Vorbis is from the alienized rpm packages from
www.vorbis.com, X is the basic Potato installation version.  Audio
is from OSS Yamaha DSXG driver.
