OpenSUSE PS3 Problems

I’ve recently installed OpenSUSE on my PS3 (I think it’s 11.1, although I can’t remember off the top of my head) but the fonts are so small that I can’t read anything. I’ve tried changing the resolution on boot but I’m not sure if I’m choosing the right ones and even then, I’m not sure if that’s what the problem is. I have a 1080i TV and I’m from the UK so it’s PAL (if that makes a difference). I presumed it’d be mode 4 that I want (or 132 if I want full screen) but mode 4 makes the task bar only half the width of the screen and it has no effect on the painfully small font.
Has anyone else had this problem or, even better, does someone know how to fix it?
Thanks in advance
