Well here is the problem with downgrading kernels, i just tried booting the Arch LTS kernel package which is 2.6.27 and i have an EXT4 root partition, therefor that kernel can't boot. Is there any good way to get an ALSA build prior to 1.0.20 to compile against kernel 2.6.33?
That's not trivial, I'm afraid.
An easier way would be to copy only sound/pci/hda/* from the older alsa-driver. If any, fixing the incompatible code only in HD-audio driver would be easier. Instead of alsa-driver tarball, you can try hda codes in 2.6.27..33 kernels.
It'd be helpful, at least, if you can figure out which version starts breaking.

after 9.04 it doesn't work, and versions of ALSA prior to 1.0.20 won't compile against the newer kernels since the source tree organization has changed
The other-way round: you can run the old kernel that old Ubuntu was based on, and compile the later alsa-driver on it.

the options in the laptop's BIOS are rather sparse and nothing about Sound card enable/disable
The soundcard works in Windows 7 and Ubuntu 8.04/8.10/9.04 Live USB images
Then try the version of alsa-driver of Ubuntu. Check whether it really works. If works, then please bisect.
thanks,
