[ltp] T42p + acpi + suspend

[Jacek Wuwer]

Thank you for sharing your experience. 
I'm travelling right now and have only limited access to my 
e-mail (through web), hence late response. 
  
I have managed to make some progress since my last post: 
- after recompiling and installing the plain kernel 2.6.10 and 
applying (cleanly) swsusp2 patches hibernate works like a charm 
(regarless of battery/ac, console/X). I guess I'll stick with 
this kernel for a while 
- suspend to ram hangs on resume (even with hibernate script 
and config) with the same message 
hda: task_out_intr: status=0x51 {DriveReady SeekComplete Error} 
     task_out_intr: error=0x04 {Drive Status Error} 
I'd like to take a look at your .config, and try to compare 
what's different 
- LCD blanking (Fn-F3) works only with radeontool  
- I have played and configured some of the scritps for 
bluetooth, ipw2200, ultrabay. Need to test the first two though  
Few questions: 
- what is the resason to compile in inird ? 
- have you got S4 and S3 work with ATI drivers ?
