mmx support with smp

Hi,

I have spent much time reading the Intel web pages. But still have
questions.

I have a video processing task that can be performed in real time using
the mmx instruction set (verified on windoz). Are the mmx extensions
supported by the kernel (during context switches etc.)? I could not
find any of the mmx instruction opcodes in the gas sources. Is it
supported in some hidden way, to be supported, or is there another
assembler?

I need speed, smp and mmx (acronym city:-( Bad as the govt;-). Does a
pair of 266 mHz Pentium IIs on an ASUS P/I-P65UP5 / c-PKND represent a
viable smp configuration? Any ideas on performance relative to the lack
of SDRAM, fp errors etc. would be appreciated.

thanks
don
