Ah, I see value in others learning from my mistakes ;)

I'm running a development version of libPNG so it's probably new code that
hasn't been tested properly.  I'm using Gentoo's unstable switch right now,
so all weirdness can be explained away quite easily ;)

Not just in the kernel... glibc is very sensitive to the options used in
gcc!

I don't even get this.  It's almost like it can't find the image.. maybe
something more fundemental is wrong.  I'm sure the path in my menu.lst is
right.. hmmmm

Which is where I was expecting to get problems with things like ALSA, but I
really don't think it is getting that far.

Very much so... :)

I'd get multiple Cray's and cluster them.. I am afterall Geoff "Dr. Beowulf"
