It really does seem to depend on the hardware. I have installed with 160 MiB of RAM and a swap partition, on one machine.  While a machine with 256 MiB of RAM and Intel video wouldn’t install, even with a swap partition. On the later machine the Ubuntu beta works but not on the former.  I haven’t been able to make much sense of it.  I have tried other LXDE based  distros such as OpenSUSE, Fedora and Mandriva ,and they exhibit similar erratic behavour.
