The layout manager provides a mechanism to remap keys to various locales
without having to rebuild the keyboard driver. If you're using the PS/2
drivers that come with PB, those already use the new model. I was thinking
of custom keyboard drivers, where the driver is included as part of the BSP
and might have been ported from earlier versions of the OS. As I said, if
you weren't using the new model, you'd probably have more problems than just
this.

I don't know where this problem is coming from, I haven't done much with
varying locales especially relating to RDP.
