PROMISE Ultra133 TX2 (PDC20269)

I have the following problem with my controller:

I have attached a 8 GB UDMA4 Harddisk, but it works only with UDMA2. The controller BIOS displays the right mode (4), but in the kernel dmesg it comes with pio. after i execute hdparm -I /dev/hde it says:

... udma2* udma3 udma4

If I try to force the UDMA4 mode with hdparm -Xudma4 /dev/hde , ... theres no difference. The harddisk leaves at udma2.

What can I do?
I have tried 2.4.26, 2.6.9, 2.6.10-rc1...

Can you help me?

Thanx, EnricoB
