GCC 3.3 compiling program with optimization for Pentium-M!?

Is there support for compiling for pentium-m with the following CFLAGS:

-march=pentium3 -msse2 -mmmx -msse -mfpmath=sse 
-pipe -fomit-frame-pointer -funroll-loops

The Pentium-M class CPU is clearly a pentium-3 based cpu with
mmx/sse/sse2 support in it's architecture.  But this seems to break one
piece of software with the following error.

{standard input}: Assembler messages:
{standard input}:1872: Error: suffix or operands invalid for `movd'

The software in question is evas-1.0.0_pre13

And no, I cannot move to gcc-3.4. I tried that once allready, and it
gave me extreeme stability problems with X and alot of other packages.

Mvh/Best regards,
