Quite a few of the BIOS on notebooks have a buggy DSDT (Differentiated System Description Table) which might leave you with a not fully working ACPI. This might render battery status, fans, sound not working. One can solve this problem with a custom DSDT in a patched initrd.
If you use a custom DSDT.aml, the kernel needs to be patched with the dsdt-patch from gaugusch.at∞ which is not integrated in the kernel from debian.org.
The good news is: the aptosid kernel is patched with the dsdt-patch from gaugusch.at.
There are two ways to obtain a fixed DSDT.aml:
Integrating your custom DSDT.aml into an aptosid system is easy:
You can even activate the custom DSDT.aml with an installed aptosid kernel. Just do:
# cp dsdt.aml /etc/initramfs-tools/DSDT.aml
# dpkg-reconfigure linux-image-$(uname -r)
# reboot
NOTE: The filename DSDT.aml is case sensitive!
