ThinkPad T43 2687-DDU setup for Debian Sarge
This is an ongoing, spotty guide for an advanced Debian setup of a T43, focused on using absolutely all of its capabilities that can be used. It is not an installation guide, but rather a configuration guide. Refer to Debian for a list of pages with initial installation instructions.
When it is really usable, I will move it to some other far more public place in ThinkWiki.
Baseline kernel: Debian's latest 2.6.15 (126.96.36.199 with stabilization patches)
- Latest ipw2200 driver and ieee80211 layer:
- copied files over the in-kernel files in include/net, drivers/net/wireless, Documentation/networking, net/ieee80211, thus replacing the old drivers with the new ones.
- SATA power-management
- freeze-block-queue patch (for HDAPS)
- ACPI update patches
- TP SMAPI support
- Software Suspend 2
- Linuxant Conexant HSF modem driver
- nsc-ircc ISA PNP patch
Kernel setup tasks
- Make sure the following subsystems are modules (for suspend/resume)
- USB (especially EHCI_HCD and UHCI_HCD)
- HDAPS (may work compiled in, as well)
- Make sure the following subsystems are enabled and not modules (safety net)
- ThinkPad SMAPI
- Place the following modules on /etc/modules:
- Configure IrDA module options
- ipw2200 firmware needs to go in /lib/firmware
- udev extended network interface naming needs to be configured, order of tg3/ipw2200 won't be respected if /etc/modules.conf is read after udev did the PCI coldplugging
Debian Sarge software packages
Some packages need versions far more up-to-date than those available in Sarge to properly support the new kernels.
- udev (backports.org), due to Linux kernel 2.6.15+
- hibernate (backports.org), due to Software Suspend 2 2.2+
Software that needs packaging/backporting
- hdapsd (a bit crude, needs a lot of work still)
- pcmcia tools (verify if not already backported)
- hal (!)
- ipw2200/ieee80211 need adopting, and since they clash terribly with in-kernel support, they will only work right if we either convert them to be patch-based, or to detect that the user built with in-kernel ieee80211/ipw2200 enabled and abort the out-of-tree compilation.
Software that could benefit from re-packaging
- hsfmodem: should be easy to build out-of-tree in another machine other than the one it will be installed at
