>Description:
	My new Toshiba M5L laptop has an ATA controller which is unrecognised
(and is therefore used as a generic UDMA33 chip).  The attached patch adds
support for this.  In adding it as ATA_I82801GB_M, I have renamed the existing
#define of the same name from ATA_I82801GB_M to ATA_I82801GB_AHM (as the
associated PCI ID is the AHCI version of the chip I have according to
page 18 of http://download.intel.com/design/chipsets/specupdt/30701412.pdf )
>How-To-Repeat:
	N/A
>Fix:
	Patch is against HEAD
