[ltp] Feisty to Gutsy dist-upgrade

[Phil]

I'm keen to upgrade my Feisty installation to Gutsy, but nervous as a 
working environment is vital.
I'm running a T60 with ATI Radeon Mobility X1400, and Intel Pro/Wireless 
3945ABG wireless card.
Can anyone who's performed this upgrade summarise any issues they've 
had, if any?

Feisty is running fine, it suspends/resumes (most of the time!), and all 
the special keys that I care about work (including brightness) and I 
don't believe it has suspend power consumption issues.

I also want to keep twin-head working. I'm currently using fglrx and 
although it took some experimentation it's now working fine with 
extended desktop over ldc and external monitor, and I can happily switch 
between single-head and dual-head without restarting X. I wouldn't want 
to lose this functionality.

Thanks for any advice.

Cheers
Phil
