Have you booted off the CD/DVD and ran FSCK?

The error message looks to me was the booting process couldn't find the root filesystem on the disk. The link you provide is something to do with re-installing boot block. Try to mount the root filesystem from the DVD, find out the disk controller, target, disk and slice number, ie (c?t?d?s?), compare it in /etc/vfstab file.

If you couldn't find files on your disks, only way could do is re-install the OS. Do you know how could this happened before the reboot?

I suspect that the application support tried to install a patch, but they do not admit it

Its weird I can't find /etc when I boot the system on a single user mode with the solaris dvd

Patching shouldn't cause this kind of problem, unless someone deleted files under /etc directory. Do you have any OS backup around ? The root filesystem could be on other slice, ie, s1, s3 etc ... ?
