I would recommend against it...

Why don't you reload it (That is if someone hasn't revoked O/S user
privileges on the DLL)?

From the help file: 

sp_addextendedproc [@functname =] 'procedure',
   [@dllname =] 'dll'

Arguments
[@functname =] 'procedure'
Is the name of the function to call within the dynamic-link library
(DLL). procedure is nvarchar(517), with no default. procedure
optionally can include the owner name in the form owner.function.
[@dllname =] 'dll'
Is the name of the DLL containing the function. dll is varchar(255),
with no default.

So....

exec master.sp_addextendedproc @functname='xp_cmdshell',  @dllname
='xpstar70.dll'

Check the DLL name I am not sure if this (xpstar70.dll) is the correct
one, its been a while since I got my hands dirty :)
