If your still adamant on using 2009.1 then at the boot splash screen press F6 for kernel options (f6 is kind of light blue so it's hard to see). In Safeboot, or Copy2ram mode.
type noscsi at the end of all the boot options.
For the old Synaptic repositories you can add a new one
main extra nonfree kde
(and unmark the others)
I really thing all Linux distros should have a long term for their classic versions. One of the main reasons for a new version is for Flash 10.
Yet, I can still get it using 2009.1 and Opera 11.
BTW, Opera 10.10 stll works better. Go figure.
