When I, on the G5, run:

growisofs -Z /dev/hda -dvd-video dvddir

I get:

ide0, timeout waiting                   for dbdma command stop
ide-cd: dma error
hda: DMA disabled
hda: dma error: status=0x50 { DriveReady SeekComplete }
hda: dma error: error=0x00
cdrom_newpc_intr: 4 residual after xfer
cdrom_newpc_intr: 4 residual after xfer

And hdparm shows the drive to no longer have DMA turned on, which it did
before running growisofs.

The same command on a B&W G3 runs fine with DMA (2.4.23 kernel).

So, to answer your question, it seems it does not work, no.
