I already did some code to support both:

#ifdef linux
    QString devname = device.mid(5);
    QString model = "/sys/block/"+devname+"/device/model";
    if (!QFile::exists(model))
        model = "/proc/ide/"+devname+"/model";
    QFile file(model);
    if (file.open(IO_ReadOnly))
    {
        QTextStream stream(&file);
        device = stream.read();
        file.close();
    }
#endif
    return device.stripWhiteSpace();

Even better, we could implement methods for GetDefaultCDDevice(),
GetDefaultDVDDevice() as well.
As a start they could just return the default drive, then if we get
complaints from users we could think about implementing a popup for the
default burner etc.  However, I do wonder how many people actually have
more than two drives (or even one) in their systems...

Well, I've been trying something like this:
    /*Needs to be editable for mac/windows since we don't (yet) detect
devices
    * automatically for those OS's. */
#ifdef linux
    bool editable=false;
#else
    bool editable=true;
#endif
    HostComboBox *gc = new HostComboBox("CDDevice", editable);

If we are properly detecting the drives there is really no need for it
to be read/write.  If Myth is still unable to detect the drive then it
suggests the users system is somehow misconfigured.

Cheers,
