cdrecord and multisession audio/data cd's?



I'm trying to use cdrecord to master a CD image to boot my Dreamcast..
Several sights say to master a 2-session cd, with the first session
containing an audio track and the second containing your raw data image
(in XA1 format).

Several places on the net give the following commands to do this:
cdrecord dev=0,0,0 -multi -audio audio.raw
cdrecord dev=0,0,0 -multi -xa1 data.raw

(data.raw is a mkhybrid iso9660 filesystem, with the first few sectors
overwritten with some boot code for the dreamcast)

however, i've tried this sequence on two very different cdr's (an old
trusty Toshiba SD-1002, and the newer sony CDRW/DVD in my i-book.) and i
can never get cdrecord to record the second session (the first completes
fine).  The second always fails complaining about cannot open a new
session/blah, illegal status ok, illegal arguments, etc.

I've seen similar reports with errors posted on the web, some trying to do
exactly what i'm trying to do, and everyone blows the off claiming it's a
hardware, media, or firmware bug... I suppose that's possible, but I've
never had problems with the toshiba before, and teh sony's brand new, so
i'm a bit confused...

Has something changed in cdrecord since these writeups were written
(between 2 years ago and 6 months ago) that won't allou you to burn a
multi-session cd with an audio track as the first track anymore?  I've
verified the raw image I'm using was created with the correct -msinfo
offsets, etc.. I'm running out of ideas...

I'm using cdrecord 2.01a19 on the ibook and  2.01a18 on the toshiba.. I'm
going to try downgrading and see if i have better luck..

any thoughts on what's going on?
tia,
