I tried building a custom initrd --with a series of modules that I 
thought might fix exactly the kind of scenario you describe. I didn't 
get it to work though but that might be because i was using the wrong 
set of modules.

How could/should this be fixed? what modules provides/supports the sata 
driver?

Any ideas?

Thanks
