intelfb stack usage

In 2.6.10-rc3-bk6, intelfb_set_par() has the distinction of being
the largest stack user as determined by 'make checkstack':

objdump -d vmlinux $(find . -name '*.ko') | \
perl /mnt/src/linux-2610-rc3-bk6/scripts/checkstack.pl i386
0x00001317 intelfb_set_par:				2404

because it has this large struct on the stack:
	struct intelfb_hwstate hw;
(almost 2400 bytes)

Any suggestions for how to alleviate this large stack usage?

From a quick look, this is called from fb_ioctl() to fb_set_var()
to fb_set_par().
fb_ioctl() does acquire_console_sem(), so using kmalloc()
here would need to use GFP_ATOMIC...
I can do that if it's desired & acceptable.
