kernel headers 2.2.18pre21-ide

["Oliver Drechsler" <eddoliv@edd.ericsson.se>]

hi all,

i need to install a driver .
i compiled the driver for my 2.2.18 kernel with the kernel headers
2.2.18pre21.
but after insmod .... my system returns kernel modul version mismatch.

my kernelversion is 2.2.18pre21-ide but i can`t find the kernel headers for
2.2.18pre21-ide.

somebody know where i can find them.

thanks for help
oliver
