QNX-Partition/GRUB

Hi, I m new to the englsih list of Suse. Maybe somebody is able to help.I m using QNX and SUSE on the same Box. Now I want and use GRUB bootloader.Is anybody doing the same and can tell a little bit of feedback.Also concerning reading each other filesystems I m interested.I build the QNX support in my kernel and also when I boot the system I can see message like QNX 2.x.y is registered but when I try to mount the partition i get the message filesystem qnx4f is not supported by the kernel. Thanks for any feedback Gottfried
