Booting laptop freezes when loading ehci-hcd

Description of problem:
The 2.6.13-* and 2.6.14-* kernels freezes (completely locks up without an error message) when booting on my Asus A6K notebook. This device contains a sis chipset, nVidia graphics and an AMD Turion processor (x86_64).
By editing the initscript I found out the freeze occurs every time just after loading the ehci-hcd module (and before trying to load any other module). This does not occur when booting a 2.6.12 kernel or previous.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot laptop with 2.6.13 or 2.6.14 kernel
Actual Results: Lockup during rc.sysinit
Expected Results: A happy machine
I have no idea if this module can be disabled in any way to make the kernel at least boot. However, I believe there is a serious bug in the ehci-hcd module that needs to be fixed.
Would you give me the precise version of that "a 2.6.12 kernel" which worked?
Then I could look for changes.
2.6.12-1.1456 is the last one that worked... with this kernel ACPI didn't work
For the record, kernel-devel-2.6.14-1.1644_FC4 still has this problem.
That had to be kernel-2.6.14-1.1644_FC4 ofcourse.
Furthermore I'm absolutely positive that ehci-hcd is the problem. I've altered
rc.sysinit to skip loading ehci-hcd (mean little if-statement :p), and with that
if-statement the laptop boots perfectly fine. I don't know what the loss in
functionality is with this alteration thou, but it's a bug that needs to be
Thanks for your help so far by the way.
