Joerg is correct about this.  I just went through the cdrecord sources
(from Fedora Core 5 with a DVD patch) and took a quick look at what
commands and mode pages were used by the different files.  I've
probably missed a few things, but this ought to give you and idea
about what is needed to burn a CD:

drv_philips.c -- Philips/Yamaha/Ricoh/Plasmon

    Commands:

    0xE2 -- Philips First Writeable Address
    0xE4 -- Philips Reserve Track
    0xE6 -- Philips Write Track
    0xE7 -- Philips Medium Load/Unload
    0xE9 -- Philips Fixation
    0xEC -- Philips Recover?
    0xEE -- Philips Read Session Info

    Mode pages:

    0x21 -- Philips Write Track Info?
    0x23 -- Philips speed select
    0x31 -- Yamaha speed select

scsi_mmc.c - MMC-3

    Commands:

    0x46 -- MMC Get Configuration

    Commands:

    0x01 - Rezero Unit
    0xE2 -- Set Mode?
    0xE3 -- Fixate/Finalize

    Commands 0xC1, 0xC3, 0xC6, 0xCE, 0xCF and 0xDF are also in the
    code but are never used.
