i have not seen this problem, but in arch/i386/boot/setup.S
there are several things that poke the keyboard. the repeat
is set, some a20 gate stuff is poked and there keyboard ctlr's
buffer is emptied. plan 9 leaves a lot of that stuff alone.
to be honest, this seems unlikely but you could try compiling
linux kernels commenting out the various bits that fiddle
the kbd controller. otherwise there's a chance of interaction
between usb legacy mode emulation and linux' usb stack.
