This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
and PC-ish keyboard controller. (Actually, on alphas, the built-in PPI
(in the SIO) appears to be a lobotomized version of the original, but
i'd not call that a bad thing.) This driver should eventually handle all
speaker tone requests and keyboard commands, but for now it just maps
the relevant ports and passes them on to the keyboard and mouse drivers,
which are now its children (rather than children of ISA).
