    unfortunately this was an April Fools joke [and luckily I didn't receive
    the wrath that Adam did for his.... yes coincidentally he lives on the
    same campus as me, but we acted independently! ;)]

    as far as I know the only way to get those messages on an Apple IIe is the
    following:

    10 PRINT "LINUX 6502 BOOTING"
    20 PRINT "Found Apple IIe enhanced, enabling lowercase."
    30 PRINT "Linux version 2.3.99-pre4 (vince@cider) (gcc version ";
             "egcs-2.91.66 19990314 (egcs-1.1.2 release)) #1 Fri Mar 31 ";
             "23:49:34 EST 2000"

    etc....

    but you might want to check out the LUNIX project...

    http://www.heilbronn.netsurf.de/~dallmann/lunix/lng.html

    they have a Unix-like kernel [w tcp/ip even!] booting on Commodore 64's,
    and with a very slow-moving port to the Apple IIe [which is crippled by
    not having a timer interrupt] and other 6502 architectures...
