I've said to use bigger images than a tiny 6MB bios updates :). Indeed, 
with DragonFly GUI iso it looks much better:

Track 01: 1161 of 1161 MB written (fifo 100%) [buf 100%]   2.0x.
Track 01: Total bytes read/written: 1218379776/1218379776 (594912 
sectors).
Writing  time:  477.630s
Average write speed   1.8x.
Min drive buffer fill was 99%
Fixating...
Fixating time:   29.040s
cdrecord: fifo had 18591 puts and 18591 gets.
cdrecord: fifo was 0 times empty and 18508 times full, min fill was 89%.

So, I'd say "please commit". Steve, can you test it with your drive(s) as 
well?
