Switching to 64 bit

[Frank McCormick <debianlist@videotron.ca>]

I am running 32 bit Sid and am thinking about a new computer which
has a 64 bit Intel CPU. How much of a hassle will it be switching
my installation over ? I know there are some problems with Flash but
what about the kernel and so forth- I am not a newby but this is the 
first time I've considered a a major change.

Thanks for any advice.
