I think I've deduced what is happening here. The combination of the dhcp-host line and the /etc/hosts entry generates the equivalent of

dhcp-host=name,192.168.X.X

When you run Ubuntu, the DHCP requests send the name, so dnsmasq find and uses this line, and all is good.

When the machine was rebooted with the install disk, the name is not sent. At DISCOVER time, the 192.168.X.X address gets offered, because that machine (based on MAC address) already has a lease on the that address. At REQUEST time, the address is disallowed, becasue it's been set as a static address for another machine (remember, no name to match the dhcp-host line.)

This hasn't been seen often, because most people nail down static addresses using the MAC address.

Given that, this should be fairly easy to fix: I believe that

http://www.thekelleys.org.uk/dnsmasq/test-releases/dnsmasq-2.48test6.tar.gz

will do the trick.

Cheers,
