Default UDMA5 Drive, But Can't Enable Past UDMA2

I'm trying to configure my Western Digital 40 GB ATA100 drive to use UDMA5, but I can't get it there. I've tried using hdparm -X69 /dev/hdb, but when I run hdparm -i /dev/hdb, it stills shows UDMA2.

I'm using RedHat 7.2.

uname -mpsr:
Linux 2.4.7-10 i686 unknown

output of hdparm -vi /dev/hdb

/dev/hdb:
multcount = 16 (on)
I/O support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 4865/255/63, sectors = 78165360, start = 0

Do I need to compile the kernel with support for VIA hardware at this point?

NorthBridge: VIA VT8363
SouthBridge: VIA VT82C686B

Thanks,
Phyre
