SRAM 8 to 9 speed compatability?

I have an 8 speed Dahon Mu SL - it needs a new cassette and chain, but before I buy a straight replacement, I thought I'd ask if anyone knows if a 9 speed cassette will fit the standard hub (it's got an SRAM X7 rear changer which I understand is 8/9 speed compatible, so I'd only need to change the trigger shifter if I go 9 speed).
The 2007 onwards Mu SL is already 9 speed, so I'm hopeful that the rear wheel is the same as my bike, in which case it should be a straightforward change (and the oracle that is Sheldon Brown suggests that Shimano/SRAM 8 and 9 speed casstetes should be interchangeable). Anyone able to confirm?
Thanks in advance......

    cassette straight on as they are the same width. new shifter and 9spd chain needed as well,and the front mech may not shift quite as smoothly.

    thanks for the quick reply - no need to worry about the front mech (single chainring) so looks as if I can do the upgrade :)
