This still applies, but I'd like to add a suggestion for the future.

In our system, individual tests can override this default size. For  
instance, a number of tests for meta viewport use 320x240px. So a single  
size does not fit all tests. Opera would suggest adding meta information  
for test size where necessary. If anyone ends up creating and publishing  
tests which depend on a particular screen size, we would all appreciate an  
automatic way of applying that information to our test runners.
