I can't reproduce it, at least in QEMU (grub build for i386-pc).
Loading custom keyboard does change keyboard layout.

This bug is not clear, but I notice that at least in QEMU interrupt is
not disabled after startup and we never explicitly do it either. So
grub may race with BIOS for input characters. The commands mentioned in
this bug report (outb 0x64 0x60 ; outb 0x60 0x64) effectively disable
keyboard interrupt. 

@Marco: would you be willing to test a patch that does it by default?

Well, you will need to debug this, as I said, I cannot reproduce it and
bug report you mentioned does not show any debug information either. If
you are willing to compile your grub, we could add debug output to
verify what you actually get from controller.
