Sorry for the late reply, i just thought i install kernel 2.6.25 r4 and 
try again.

It is somewhat better and worse, when modprobing p54usb i got a small 
hang/hickup accompanied with the following error in dmesg
ehci_hcd 0000:00:02.2: HC died; cleaning up

afterwards the kernel fails (refuses ?) to detect the device again. so I 
no longer get a kernel oops but even modprobbing doesnt work anymore.
see attachment for full dmesg. any ideas, testing i an do now ?

kind regards,
Ivo Couckuyt
