SubjectKernel 2.6.x USB support needed for PS/2 Mouse/Keyboard to be functional

it has taken a long time to find out why I was unable to run any 2.6
Kernel (2.6.0 - 2.6.5).
The Problem is, that if I do not have usb support compiled in (or as as
my PS/2 Keyboard and PS/2 Mouse does not work and immeditley freeze when
X starts (though the
system is still running as I could see on the system clock).

Keyboard works, as long as I do not start the X server, but soon as X
has started the Keyboard freeze. The Mouse
never worked. Both work fine under 2.4.x without USB

I consider this as a bug, as this is nowhere documented that usb is
needed to run PS/2 periphals (or at least nowhere where
I looked [ Documentation/Google/kernel list])

My setup is

Microsoft Office Pro Natural Keyboard connected via PS/2 Adapter
Microsoft Optical Mouse also connected via the PS/2 Adapter

in between sits a KVM Switch.

X is at Version 4.4.0
