FWIW, on a P4/3GHz system with Intel SATA, 2.4.21-vanilla:

Linux version 2.4.21 (root@wormhole)
CPU0: Intel(R) Pentium(R) 4 CPU 3.00GHz stepping 09
CPU1: Intel(R) Pentium(R) 4 CPU 3.00GHz stepping 09
Total of 2 processors activated (11979.98 BogoMIPS).

(this is hyperthreading)

ICH5-SATA: IDE controller at PCI slot 00:1f.2
ICH5-SATA: chipset revision 2
ICH5-SATA: not 100%% native mode: will probe irqs later
    ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA, hdd:DMA
hda: Maxtor 6Y080L0, ATA DISK drive
blk: queue c0324f00, I/O limit 4095Mb (mask 0xffffffff)
hdc: Maxtor 6Y080M0, ATA DISK drive
hdd: Maxtor 6Y080M0, ATA DISK drive
blk: queue c0325374, I/O limit 4095Mb (mask 0xffffffff)
blk: queue c03254c0, I/O limit 4095Mb (mask 0xffffffff)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15

.. works fine. But it's now running 2.5.74-mm3 (also OK).
