Actually, I've tested it on another computer (AMD64):
VP_IDE: VIA vt8237 (rev 00) IDE UDMA133 controller on
pci0000:00:0f.1
    ide0: BM-DMA at 0xcc00-0xcc07, BIOS settings:
hda:DMA, hdb:pio
    ide1: BM-DMA at 0xcc08-0xcc0f, BIOS settings:
hdc:DMA, hdd:DMA
hda: ST3120026A, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hdc: HL-DT-ST DVDRAM GSA-4163B, ATAPI CD/DVD-ROM drive
hdd: RICOH CD-R/RW MP7083A, ATAPI CD/DVD-ROM drive

Unfortunately, there's still problem with that patch
with Ricoh drive:

Kernel panic - not syncing: Aiee, killing interrupt
handler!

With 2.6.13-rc1 (+Hugh's patch), all is well in this
computer. And oh, the LG DVD-RW drive doesn't crash
even in 2.6.12, though I didn't wait for more than 10+
minutes. (IOW, it must be hardware dependant.)

Thanks
Hari.

PS: I added -ide suffix to kernel version, so that
kernel build doesn't overwrite the real 2.6.12 modules
directory.
