added a function to boot/boot.c that reads #P/mpirq and prints it. opening
the file works, but read() returns 0.
i have serial console connected to the machine now so here are some dumps:

this continues on vga screen a little bit further and gives me mpintrenable
error for every
device... then boot starts, prints the empty #P/mpirq file and asks for rootfs.
the iahci stuff is just debug prints... ignore it :-)
