PATCH 1/1 Generic IDE support for Toshiba Piccolo PCI IDE chips (2.6)

Adds Toshiba IDE chips to the list supported by the generic IDE driver. The 2.4 tree already contained an entry for product:0x0102, this patch adds that entry to 2.6 as well as two new ones (0x0103 and 0x0105). This then allows DMA to be enabled on disks.

For more info, see:

http://www.uwsg.iu.edu/hypermail/linux/kernel/0402.0/0129.html
(it appears that Ben's patch never appeared, and Jerome's got lost)

Against 2.6.6-rc2

Please apply,

Daniel
