You can't use FPU operations in the x86 kernel.

Maybe you should do this in user space ? Certainly the more I talk to people
like Nicholas Pitre the more it seems to me that most of the kernel side
stuff is the wrong approach.

Instead would it not be better to

- Fix select on /dev/vcsa to work
- During init start up after init processes are running have
the init tasks (or for that matter the kernel) fire up the
speech helper

The fact 95% of the speakup drivers are going to spontaneously go
obsolete the moment serial ports vanish bothers me.
