===== Wireless card =====
  03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

Thought I have followed the directions of the kernel document,but it still can't find the wireless card,after the google search ,it must enable the following options for the kernel
  Device Drivers->Broadcom specific AMBA->
                     < *> BCMA Support
                      [*] Support for BCMA on PCI-host bus
And you can find the firmware in the 
   ls /lib/firmware/b43/
   
   
===== ALSA Sound card =====
Add the hda-intel to /etc/make.conf
  ALSA_CARDS="hda-intel"
And config the kernel options fo intel hda,after these I think it should work well,but wtf,it is no sound.I almost use alsa-mixer to set all the values to the largest,but useless.

Then one day,I use the System->Volume Control,I found some settings are set to mute,that is the problem,after correct,it works well,so strange.

==== ALSA Settings ====
Refer to [[http://www.gentoo.org/doc/en/alsa-guide.xml]]

  emerge alsa-utils
  rc-update add alsasound boot
  gpasswd -a <username> audio 
  
===== aticonfig =====
When I upgrade the kernel to 3.3.8,it can't startx correctly,after google search,need do the aticonfig to generate the /etc/X11/xorg.conf:
  aticonfig --initial

Touchpad:The touchpad works flawlessly with xf86-input-mtrack.
  
http://dentifrice.poivron.org/laptops/macbookpro8,2/

  emerge x11-drivers/xf86-input-mtrack
  
Append section to /etc/X11/xorg.conf
<code>
Section "InputClass"
	 MatchIsTouchpad "true"
	 Identifier      "Touchpads"
	 Driver          "mtrack"

===== Fix boot after reinstall Mac OS X  =====
1.Of course,first should install rEFIt,and sync the MBR partition list.

2.Fix the grub command,it is really strange,after the new install of Mac OS X,the sda5 has been changed to sda4,so need update all related partition index by -1.
<code>
splashimage=(hd0,3)/boot/grub/splash.xpm.gz
#Now config
title Gentoo Linux root (hd0,3) root=/dev/sda4 /boot/kernel-3.3.8 
root (hd0,3)
kernel /boot/kernel-3.3.8 root=/dev/sda4

#The previous config
title Gentoo Linux root (hd0,4) root=/dev/sda5 /boot/kernel-3.3.8 
root (hd0,4)
kernel /boot/kernel-3.3.8 root=/dev/sda5
</code>

And the fstab also need update:
<code>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda4              /           ext4            noatime         0 0
#/dev/sda4 /boot		ext2		noauto,noatime	1 2
/dev/sda3		/home		ext4		noatime		0 1
#/dev/SWAP		none		swap		sw		0 0
/dev/cdrom		/mnt/cdrom	auto		noauto,ro	0 0
/dev/fd0		/mnt/floppy	auto		noauto		0 0
