I've not found that to be the case.
On a Tomcat II under fairly heavy load, I've quite happily managed
"cp /dev/hda /dev/hdb1" (CDROM into first partition of HD) and then written a
CD from the IDE drive.

PIIX3: IDE controller on PCI bus 0 function 57
PCI->APIC IRQ transform: (B0,I7,P-1) -> -1
PIIX3: not 100% native mode: will probe irqs later

ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
