PA-RISC is a less compact instruction set than x86, so it'll always
be bigger. Also, the SCSI layer is bigger than the IDE layer. And the
x86 kernel is gzipped and I don't think we ever bothered gzipping the
PA kernel. Having said that, of course you can chop out the drivers you
don't need -- eg you only need the Tulip driver, and not the Lasi_82596
driver.
