Hi all,

I just found a working solution for the fglrx 8.19.10 + Suspend 2.2-rc9
running on my T41p with kernel 2.6.14 pre-empt.
problem I described in one of my last mails.

The following error occurs just when atomic copy should take place:

"Pageset1 has grown by 2597 pages. Only 100 growth is allowed for!"

The value 100 is defined as a constant in kernel/power/prepare_image.h:


So I changed this value to 3000 and suspend and resume works
flawlessly after recompiling my kernel.
There is no need for vbetool or any "XHacks".

To be sure, I contacted Suspend 2 developer Nigel Cunningham,
and this is what he says:

There shouldn't be any bad effects from increasing the value. Up until 
now, we haven't needed higher values because most drivers hardly 
allocate any memory when told to suspend. Since flgrx is allocating 
more, I can increase the value in my version too. It will just mean that 
Suspend will over-estimate the amount of memory it needs by a greater 
margin for people who don't have fglrx, and may free up a little more 
memory than it would otherwise. 

So happy trying to you all ;)
