Brute force a register save/restore for int 0x13 (disk I/O) and 0x10 (putchar)
by using pusha/popa.  Don't trust the BIOS to properly save and restore
registers.

Note that the TICKS check for boot0 currently still depends on %di being
retained across two BIOS calls.  More code reorganization is required to
make a save/restore fit in the space available.
