I'm having problems burning CDs at speeds higher than 16x too. But
disabling DRI (no radeon.o module loaded) didn't change that. I'm using
a stock 2.4.19 kernel + preemptible patch. On the console I see an IDE
reset followed by "failure to handle paging request in kernel" and
finally a kernel panic "killing interrupt handler\ninterrupt handler not
syncing". CAPS lock and scroll lock LEDs blink.

Try it in dummy mode, if you're just testing ;-)
