Mostly true, though there are now no problems getting flash to work.
Running the x86_64 5.0.0 K12LTSP release, I simply clicked the 'Get
flash' icon, which adds the flash plugin to the i386 firefox. There is a
wrapper script written by some genius that, whenever you start firefox,
runs the x86_64 firefox in 64-bit environments, and the i386 firefox (w/
flash) in i386 environments (the terminals). It could not have been easier.
