a few questions regarding acpi and kernel configuration

a few questions regarding acpi and kernel configuration

[Littlefield, Tyler]

Hello all:
I have a few questions, I was hoping someone could help me out here.
First, I'll start off by saying that my netbook is a sort of PDA for me. 
I just boot it up and when I'm taking care of stuff for work running 
around getting info and that, I can use it to grab the info. I use Linux 
for this, but my battery dies kind of quickly. I'm also looking to 
optomize performance as much as possible.
So, I sat down and tried to optomize a kernel. Both to save space (since 
this is a smaller drive), and to make things a bit quicker, even by a 
little bit.
I put the config here:
http://tds-solutions.net/config.tar.bz2
First, I'm curious what else I can yank out of there to make everything 
smaller. I'd like to cut down on the drivers and all that, and just 
include the driver for my specific harddrive if that's possible, as well 
as the wireless card. Can I turn off scsi/pata/ata since I have a sata 
drive? Is there other stuff I missed that I could take out?
Finally, my last two questions.
1) Is there a way to access acpi so I can put the computer into standby 
quickly? I'm not sure how to pull that off from the cli, but doing it 
with code would work.
2) Is there a way for me to detect when the lid of my laptop has been 
closed and put it into standby, and/or set an idle timer to put it into 
standby? If there are clients out there that can interface with acpi and 
help with this, awesome. If not, and I need to code something up, that 
works too.
Finally, I'm trying to find a way, since I do not use it to turn off the 
display. Is this possible?

If you are referring to Suspend-to-RAM here, you can install the 'pm-utils'
package and then run the 'pm-suspend' script from the cli to suspend
the machine.

Most distros can be configured to do all that. You need not have to code
anything new. You'll just have to set up the power management policies
appropriately to tell what should happen when your laptop lid is closed
etc.

a few questions regarding acpi and kernel configuration

[Pritam Bankar]

Hi, 
To cut down drivers you should configure your .config file in your source.
You will have to recompile kernel.
For pata you have ,

CONFIG_PATA_AMD=y
CONFIG_PATA_OLDPIIX=y
CONFIG_PATA_SCH=y

This can be set to "n" instead of "y" to remover support of pata. This can
be done to other modules also.
