Not sure if it is related, but as of Jan 30 2010 my Wubi installation failed to boot. After selecting the 2.6.31-16 kernel in the GRUB menu (the default entry), the console reports a "compression error" and then claims that no root filesystem can be mounted. Selecting the 2.6.31-14 kernel works fine, after which 'ls -lt /boot' shows that initrd.img-2.6.31-16-generic has been modified on the 30th (but not vmlinuz-2.6.31-16-generic, which was rather older). 'gzip -t' reports no errors on it.
