Do you think that ext3 (or ahci, libata etc) is built-in to any modern sl 
kernel?

If you didn't already know the initrd contains all the kernel modules 
which are needed to get you into a state where the root fs can be mounted.

Normally mkinitrd (which is run during a kernel install) will attempt to 
work out which modules are needed - e.g. hardware drivers for scsi, sata 
etc, as well as any filesystem modules.

If you manually call mkinitrd you can specify extra modules on the 
command-line which will be fine until you next do a kernel upgrade.

Probably best to look at the mkinitrd man page (and code) to find the 
simplest way for what you need).  Of course that will be easy compared to 
getting the initrd to actually mount your squashfs as / (if you don't 
need it to be / then it could be mounted after the real / is available)...
