Hi Adam,

I had a similar problem. I thought i found the reason on the cdrecord
web site, but having just scoured the site I can't find the reference.

It went something like this. The precompile binary for cdrecord v 1.10
was compiled on a 2.4 kernel. This kernel supports mmap. Older kernels
(eg: 2.2.*) doesn't handle mmap correctly. Looking at some other problems
on cdrecord's site, hand compiling cdrecord v1.10 by hand might fix it.
I just used the stable deb package (which breaks xcdroast on upgraded
systems).

Ahh, and just as i finish i find this

So it looks like it will work if you compile cdrecord yourself.
