Yes, it's strange. And take NEC's Markham and Korva network processors
(Vr4100+ethernet+system control+ATM+USB on a single chip): they happily
incorporate a 64 bit CPU, but allows a max 32 MB RAM! And a 4 MB memory
window only on the PCI :-( I'd rather have a MIPS R3K PLUS LL/SC
instructions than the Vr4100 core on that chip.
