Some CD devices do not implement DMA support 'correctly'.  Using this parameter forces all CD like devices (CD, CD-writers and DVD drives) to use Polled I/O mode, which is definately 'slower' for most DASD (Hard drives), but may not appear slower for CD drives.  If you use the ide=nodma parameter, you can see the effect of placing the entire IDE interface in PIO mode (it is much slower than DMA mode.)
