My suspicion is that it is booting, just that the graphics card (driver) is messed up sufficiently that it's not able to bring up an image. If you're able to boot from the CD/DVD, you should be able to change the boot entry to add the keyword 'text' and remove the gfxmode. If this works to boot it, but you're still having trouble with seeing the screen at the end of the boot, then it's definitely a graphics driver issue.
You might be able to do a recovery install with the DVD, without erasing the contents of /home. Alternatively, if you've discovered that the system is indeed booting (but you just can't see it), but you previously activated SSHD, you should be able to SSH in and backup the files that you want to see before attempting a reinstall. Another approach is to pull the graphics card, connect your monitor to the built-in graphics adapter, and boot that way. I've found that some systems will come up that way when the graphics driver is screwed up after an update.
