I have two of the Mk2 and one of the Mk1 keyboards and none of them exhibit 
the problems you have (using 3 different systems with kernels both 
2.4.18-pre7-ac2+ide+other stuff, 2.4.18-pre3+ide+other stuff and 
2.5.24+ntfs-2.0.13). The difference being I am using the full HID drivers 
(I tried both) and never the cutdown usbkbd driver. (I have many other usb 
devices including my mouse, digital camera, webcam, etc, so can't use usbkbd.)

So as other people have suggested, use the full hid driver and be happy. (-:

Best regards,
