IMHO it's misspelling. In general SSE2 of P4 is differ from SSE1 of P3 from program
point only by 144 new opcodes, cache architecture and by little extensions for
multiprocessor support. There are no new registers to be saved. And probably there
are no new environment to be saved.
#The signal handling one is because 2.4.x will save off the full SSE2
#state, which means that the signal stack is almost 700 bytes, as
#compared to <200 before
but it you'll compute size of required environment for P3 (SSE1) you'll get over 200 bytes
only for register of application level (XMMX+MMX+ERX).
I've tell it to stop any disputs about usage Linux-2.2.x on P3.

Best regards! Nick
