That sounds more like a problem with your samba configuration - samba 
supports EAs (it'll even map them directly to Linux EAs if configured to 
do so - set 'ea support = yes' in your smb.conf) and copies them around 
quite easily.

EAs on NT are used for lots of things - some AV uses it to mark scanned 
files, for example, and every file on XP has them by default (right 
click, properties, select 'summary' - this is all EA).

It's a feature - it holds the unix compatible bits of the file, so you 
don't lose them when you edit on NT (it also happens to be readable by 
cygwin when required).

cvsnt is going to use them a lot more in the future (since they offer 
some nice advantages on systems that support them) so it's best to get 
them working rather than disable them.
