I wasn't expecting it to work 100% flawlessly out of the box. But not even able to boot? I feel sorry for Canonical as 10.04 is an LTS release, so they're now stuck with this rather glaring incompatibility for years.
LTS versions have stable patch-level releases every 6 months while they're supported (e.g. 10.04.1 was released in July, and there will probably be a 10.04.2 in January), so they're able to add drivers to the installer when they become available.
