What probably happens is that when you start e.g. a Web browser, a
whole bunch of scaled fonts are generated. Without a math coprocessor,
this takes quite a while. The solution, from what I remember, is to
change the order of the fonts in your /etc/XF86Config, to make X find
the fixed-size fonts first.
