ali_pata sets my udma to 33 when it should be 66

I just upgraded my HP N5430 laptop to fedora 7 with a 2.6.21 kernel.
It used to be udma/66 under the old ide driver.

ata1: PATA max UDMA/100 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x00011000 irq 14 ata2: PATA max UDMA/100 cmd 0x00010170 ctl 0x00010376 bmdma 0x00011008 irq 15

scsi0 : pata_ali
ata1.00: ata_hpa_resize 1: sectors = 39070080, hpa_sectors = 39070080
ata1.00: ATA-5: HITACHI_DK23CA-20, 00H1A0A3, max UDMA/100
ata1.00: 39070080 sectors, multi 16: LBA
ata1.00: ata_hpa_resize 1: sectors = 39070080, hpa_sectors = 39070080
ata1.00: configured for UDMA/33

How can this be fixed?

Thanks,
Steve
