Please re-test against 2.6.15-rc1 *plus* the EHCI patches at  
Either see the "usb" subdirectory (use "quilt", or at least the 
apply in the order shown in the usb/series file) or the toplevel 
USB patches. 
One odd thing:  didn't look like EHCI was getting its PCI resume call.

2.6.15-rc1 alone : same problem
2.6.15-rc1 +
: kernel panic

is it another patch ?
