Note that the fact that the keyboard working when acpi=off seems to be
that udev don't probe parport* stuff in that case. I inserted parport by
hand and the keyboard is gone again as well:

[ 30.696938] parport_pc 00:0d: reported by Plug and Play BIOS
[ 30.697000] parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE]
[ 30.780388] lp0: using parport0 (interrupt-driven).
[ 30.804130] ppdev: user-space parallel port driver
