ATA 100 & VIA and linux-2.4.3ac8

[Manuel Ignacio Monge Garcia <ignaciomonge@navegalia.com>]

	Hi. I have a ASUS A7V133 Motherboard  with AMD ThinderBird 1 Ghz, and 
PDC20265/VIA. I've tried all the possible combinations on "IDE, ATA and ATAPI 
Block devices". I've read the "Unofficial Asus A7V and Linux ATA100 
"Quasi-Mini-Howto" on http://www.geocities.com/ender7007/. But I still can't 
use de IDE UDMA100 controler. I see some messages with this options on 
earlier version of the ac-kernel, so I guess what I need to do the right 
thing. My current kernel is 2.4.3-ac9.
Some settings:

a) "IDE, ATA and ATAPI Block devices" config in the kernel:
	CONFIG_IDE=y 
	CONFIG_BLK_DEV_IDEDISK=y
	CONFIG_BLK_DEV_IDECD=y
	CONFIG_BLK_DEV_IDEFLOPPY=y
	CONFIG_BLK_DEV_IDESCSI=y
	CONFIG_BLK_DEV_IDEPCI=y
	CONFIG_IDEPCI_SHARE_IRQ=y
	CONFIG_BLK_DEV_IDEDMA_PCI=y
	CONFIG_IDEDMA_PCI_AUTO=y
	CONFIG_BLK_DEV_IDEDMA=y
	CONFIG_BLK_DEV_PDC202XX=y
	CONFIG_BLK_DEV_VIA82CXXX=y
	CONFIG_IDEDMA_AUTO=y
	CONFIG_IDEDMA_IVB=y
	CONFIG_BLK_DEV_IDE_MODES=y

b) cat /proc/ide/via output:
