Spaces in Grub parameter. Kernel Panic "bad variable name"

Hi,

i try to setup two different framebuffer resolutions.
I've got an ATI HD5700 using the radeon driver, kms enabled.
My connector identifiers should be "DVI-I-1" and "HDMI Type A-1".

ls /sys/class/drm

card0
card0-DisplayPort-1
card0-DVI-I-1
card0-HDMI Type A-1
controlD64
ttm
version

I use the following kernel line in my menu.lst:

kernel /vmlinuz26 root=/dev/sdb3 ro radeon.modeset=1 video=DVI-I-1:800x600-24@60,HDMI Type A-1:1920x1080-24@60

This does not work, i always get kernel panic:

/init: export: line63: A_1:1920x1080_24@60: bad variable name
Kernel panic - not syncing: Attempted to kill init!

The whitespaces in "HDMI Type A-1" are the problem, i think, but i dont know how to avoid this.
I tried several kinds of escaping but nothing worked for me.

I found this: https://patchwork.kernel.org/patch/198472/ (no help for my, my english is not the best)
and this: https://bbs.archlinux.org/viewtopic.php?pid=431030 (adding a "#" before "video="didnt help)
