Chromium requires sse2 normally, as detailed in this bug report:

http://crbug.com/9007

I don't have PIII hardware to test: what you can do is 'make patch', 
then go into 
work/chromium-courgette-redacted-5.0.375.127/build/common.gypi and find 
these lines

                   '-march=pentium4',
                   '-msse2',
                   '-mfpmath=sse',

and comment them out, then build as normal.  I think that should work. 
I don't know what ports normally does to support older hardware like 
this, but we can consider adding a patch for the 6.0 update if necessary:
