having a very similar issue with my second gen non-intl g5.
This morn, net connection dropped. Didn't think much of it. Reboated router and modem, and g5.
On startup, this is where things got hairy. Gray screen with apple logo, and fans running constantly, loud.
-Could not boot in safe mode.
-Booted from Leopard install disc, and performed a disc repair, unsuccessfuly gave me error "disc could not be unmounted"
-Performing reinstall of Leopard now (taking 3 hrs now, way longer than when i upgraded)
Seems when i upgraded to leopard 3 months ago, the machine starting running way hotter than previously, and fan ran more often. Could this have affected the disc?
Haven't heard of many macs overheating under similar conditions as mine.
