I've tried it, and that part works fine.

I believe you can use up to but *not* including 4096kB. I just tried
cdrecord with fs=4000k and that went fine (at least in dummy mode,
haven't tried a real write yet).

First I had to hardlink /usr/bin/cdrecord to
/usr/lib/xcdroast-0.96d/bin/cdrecord-1.6 as otherwise xcdroast thinks
that "not all the binaries are installed".

The setup mostly works, expect that changing the cdrom / cdrecorder
things via the buttons gives an error: 

    can't read "tkPriv(activeMenu)": no such element in array

For those who understand tix, the stack trace shows:

   can't read "tkPriv(activeMenu)": no such element in array
       while executing
   "string compare $tkPriv(activeMenu) $menu"
       (procedure "tkGenerateMenuSelect" line 4)
       invoked from within
   "tkGenerateMenuSelect $menu"
       (procedure "tkMbPost" line 28)
       invoked from within
   "tkMbPost $tkPriv(inMenubutton) 816 272"
       (command bound to event)

This looks like some incompatibility with the (current?) version of
tix (or tcl/tk). It happens on all choice-list buttons.
I tried upgrading to the newest of all of these, and rebuilding the
current frozen xcdroast version, but no improvement beyond what I list
above.

I'd definitely go for cdrecord.
