Ubuntu Gutsy 7.10 Tribe 5
Unofficial Lowlatency Kernel Package
for Thinkpad T30 laptop with Docking Station support
[not tested on any other T series laptops but may also work]

1. First we need to install new downloaded kernel and kernel headers:

 dpkg -i ./linux-image-2.6.22.7-t30-rt_2.6.22.7-t30-rt-10.00.Custom_i386.deb
 dpkg -i ./linux-headers-2.6.22.7-t30-rt_2.6.22.7-t30-rt-10.00.Custom_i386.deb

2. To build and start realtime module, boot from the new kernel and
type:

 $ sudo -s
 # apt-get remove apparmor
 # rmmod apparmor
 # rmmod commoncap
 # m-a update
 # m-a prepare
 # m-a get realtime-lsm
 # m-a build realtime-lsm
 # m-a install realtime-lsm
 # echo realtime >> /etc/modules
 # modprobe realtime

3. To install MadWifi drivers for Atheros (only if you are using one,
because they are not included in kernel package) type:

 $ sudo -s
 # wget http://downloads.sourceforge.net/madwifi/madwifi-0.9.3.2.tar.gz
 # cd madwifi-0.9.3.2
 # make clean && make && make install
 # echo ath_pci >> /etc/modules

4. Reboot laptop to test new kernel:

 $ sudo reboot

5. In IBM BIOS -> Config -> Power, change Power Mode options to
Customize and LCD Close Suspend to OFF, because we want standby mode
when closing LCD panel.

6. Boot from new kernel (you can add vga=791 kernel parameter to use
framebuffer console at 1024x768 - fbcon is compiled into kernel)

7. Even if you see some irq errors, USB#2 in Dock, PCI and PCMCIA cards
should work. If not, try to boot with PCMCIA USB 2.0 with connected
devices card plugged in and after boot, connect device you need in Dock
USB#2 port.

 $ sudo -s
 # rmmod ohci_hcd && rmmod uhci_hcd && modprobe uhci_hcd && modprobe ohci_hcd

8. You don't have to do additional changes to /etc/modules or /etc
/initrd-tools/modules or start kernel with any additional parameters.

9. Remember that if you have any Ubuntu kernel installed from any
repository, your menu.lst will change and default kernel option can be
replaced after update.

10. This kernel is unofficial, so don't bother Ubuntu team about it -
you can bother me instead, but you are using it at your own risk.
