ATI Radeon on Vaio Laptop

[M§K <kr1st0@yahoo.it>]

Hi everyone,
I already posted a (sort of) detailed explanation of my problem on other 
lists and newsgroups, but I got no reply, so I was wondering if the 
answer was up on the top of the matter; I'll put it simple: is it 
possible with XFree86 to have screen resolutions lower than 1024x768 on 
mobility radeons with XGA TFT 15' display?
I mean, I tried with windoze and it actually worked, but the doubt 
whether this is a sort of hack not supported by XF86 or not came to my mind.
I apologize in advance if it's a silly question, but, as I said before, 
posting XF86Config-4 abstracts or X server logs lead me to no answer, as 
well as searching on FAQs and forums.
Of course I hope the answer is positive and we can discuss the issue 
more into details...

Thanks
M.
