I have been reported this bug since the first beta, but we had no feedback. It seems that this problem is difficult to correct, since the IDE code is completely rewritten for the 2.5 kernel (and subsequently the future 2.6). It seems that there are patches from Alan Cox, or Andre Hedrick on http://www.linuxdiskcert.org/
I don't know if they can be applied on the mandrake kernel without breaking other things. What is sure however is that the Salckware 8.0 kernel has been correctly patched, and hdparm works with the i845e/g chipsets. Now only mandrake programmers could answer this question, but I never had any comment since the release of beta2 about that issue...
