Bug#489190: Solved
The noloop trick worked for 2.6.24 but failed for 2.6.25. I wrote to
Dmitry Torokhov who told me to run the kernel with i8042.debug and send
him the output of dmesg and dmidecode.
He provided this patch which fixed the problem for me:
Input: i8042 - add Arima-Rioworks HDAMB board to noloop list
The board does not raise AUX IRQ in response to AUX LOOP command.

If it still fails for you, I suggest that you contact Dmitry directly.
