I assume you have a good reason, but why are you changing the it8712f 
pnp device numbers? I am not positive how this works, but I think 
changing 2e.0 to 2e.7 means that you are trying to program the it8712f 
logical device 7 with floppy settings.

IRQ routing/polarity/mask issues? Check mptable.c and irq_tables.c.

You can check the keyboard controller input buffer to see if a keystroke 
is in there. Then you would know that interrupt isn't getting through.

Do you have serial console working and does keyboard work there? That 
would tell you if interrupts are making it from the SIO.


Hope this helps.
