I may have similar problem. I have a Dell Inspiron D600.
I can boot the kernel 2.6.9 but with 2.6.15 the laptop cannot boot.
Simply shows the kubuntu loading screen showing no progress.
If I go to VT1, there are just the very first 2 lines after selecting the kernel in grub, saying the system is starting.
No error messages.
If I try the 2.6.15 in "safe mode" the kernel starts, but when booting hungs it seems when checking some usb HW.
