There is a BIOS function that can read the keyboard.  I think you can
use this.

You have to use softint 0x16, sub function 2.  You can check if Alt is
pressed by checking bit 4 of the AL register.

Please look for Ralph Browns interrupt list for more information about
software interrupts.

I didn't look at the GRUB code so I don't know if this is usable.
Perhaps GRUB uses another way to read the keyboard, if it doesn't work
just ask me and I will have a look at the code. :)

Thanks,
