I was able to resolve the device slowdowns by rearranging the IRQ
setup via the ps2 utility after I realized that they appear on cbb[01] 
with ACPI enabled while the IRQ is shared with uhci0.

The interrupt storm error messages do not disappear for me, but 
I do not care about this while anything works like it should.

Thanks to Matthew N. Dodd for encouraging me to test all possible
IRQ setups in order to solve the device slowdown.
