mount reiserfs hda 7 ??

I'm running Suse 9.1 and WinXP, I've installed Linspire to check it out. It overwrote the boot stuff. Reinstalled XP and Suse. LOS is still on hda7 XP has the rest of hda and Suse has 30 gigs on hdb (the whole drive) I can't see the LOS partiton but I can see all the XP partitions all fat32 if it makes a diff. LOS is reiserfs. I need to mount and get hda7 Linspire into the grub boot menu of Suse. If you have time could you tell me the best way to go about what I'm trying to do? Thank You PS: I'm no guru but willing to learn and try most anything.
