Thanks for the pointers Zulus Surri. I think your analysis is correct,
although I don't have an old enough CPU handy to confirm it.
I'm afraid reverting that one change won't cut it, as it's likely that
there are now multiple changesets in chromium that take advantage of
this recent SSE3 requirement.
On a related note, we still carry a disable-sse2 patch that is probably
non-functional any longer and that was inherited from Debian long ago. I
just checked and the Debian packages don't have that patch anymore, so
it's probably safe to remove it.
