[rtl] Mapping memory

[SteenbeckDigital <steenbeckdigital@compuserve.com>]

take a look at one of the PCI drivers in ./linux/drivers/scsi/ for example.
The function is called ioremap() in 2.2 kernels

Hello,

I am having some difficulty mapping memory in my rtlinux module.  I am
attempting
to map the memory on the vga card which is at physical address 0xe2000000.
To 
attempt to do the mapping I call mmap after opening /dev/mem.  Everything
works
find and no errors are returned.  Once I try to use the pointer returned by
mmap I get the following error:

        Unable to handle kernel paging request at virtual address e200000.

Any ideas what the problem is?

Thanks
Adam
