With kernel-2.6.15 series, the program for loading Elite graphics
microcode fails:

Is this a known problem, or is the fix for afbinit known?
With the 2.6.15 kernel series (on SB1000), an attempt to load the
Elite graphics microcode with the afbinit program:
/* $Id: afbinit.c,v 1.1.1.1 1999/09/08 06:42:36 davem Exp $
(e.g., using
afbinit /dev/fb/0 /usr/lib/afb.ucode)
results in
mmap user regs: Invalid argument --- this comes from this bit of code:
====================
 uregs = mmap(0, 0x2000,
             PROT_READ | PROT_WRITE,
             MAP_PRIVATE,
             afb_fd,
             0x04000000);
====================

I'd be happy to just fix it if I knew what the mmap call should look
like with this kernel, but I don't.  (The Elite did open OK; to get this
far,
afb_fd = open(afb_fname, O_RDWR);
has to have worked.

Regards,
Ferris
