Ondrej, I see two problems with this patch: For one, on a system without i8042 the code at the place it got inserted ought to incur a stall of 1s (50us * I8042_CTL_TIMEOUT [10000] * 2). I believe that this code should not be run before i8042_controller_check() completed successfully, but at the very least the second call to i8042_command() should be conditional upon the first being successful (effectively halving the stall).
Second, considering that enabling A20 (even if just in a fake way), is a core system operation, I don't think it belongs into a driver that is only optionally present in the kernel.
