Well it sure is nice not having any issues with ift-load, but
Bjorn you're right, So I reverted back to udev were the issue seems
to be happening. FWIW here is what I see in dmesg after loading the system
without ehci_hcd and then modprobing ehci_hcd:

The first time I did this the shell's cursor moves as if I've pressed
"return" five times,
bluetooth stops working for a while then reconnects, typing on my keyboard
was printing double characters(only noticed this the first time doing this,
the second reboot typing seemed to be o.k.).
