5	If you want to trick swsusp/S3 into working, you might want to try:
6	
7	* go with minimal config, turn off drivers like USB, AGP you don't
8	  really need
9	
10	* turn off APIC and preempt
11	
12	* use ext2. At least it has working fsck. [If something seems to go
13	  wrong, force fsck when you have a chance]
14	
15	* turn off modules
16	
17	* use vga text console, shut down X. [If you really want X, you might
18	  want to try vesafb later]
19	
20	* try running as few processes as possible, preferably go to single
21	  user mode.
22	
23	* due to video issues, swsusp should be easier to get working than
24	  S3. Try that first.
25	
26	When you make it work, try to find out what exactly was it that broke
27	suspend, and preferably fix that.
