To be completely frank, I hope we find a volunteer for the debian packages too... So, actually, we could add such an announce to the wiki. >> We will also try and address the issues which were identified since you >> started working on this, namely: >> - allowing enabling the SMI workaround without kernel re-compilation > > Great!

I guess I have some little piece of code somewhere to handle configuration files with the "windows ini" style, if you are interested. The kernel-based approach has a big advantage though: recent kernels have a driver for the LPC part of the Intel ICH, which is where the register controlling SMI is found (drivers/mfd/lpc_ich.c), so, basing our work on this driver in the I-pipe kernel, we could share the table and avoid the double maintenance. -- Gilles.
