A company I work for recently bought an 040 board from Motorola, and
we discovered that they didn't put the floating point support code in
their own ROMs.  When we called them to get some help, they said they
would sell us the library for $5000!  Needless to say, we wrote the
library ourselves.

I don't know if 2.0 will have 040 support, but if it doesn't, be very
careful to ask whoever you get the board from if it has direct math
support.  If you can get burned by the chip manufacturer, you can get burned
by anybody.
