forcepae option doesn't work for ubuntu-mate 18.04 beta

[Glenn Brumfield]

Downloaded ubuntu-mate 18.04 beta for 32-bit; confirmed sha256sum. Attempted VBox install using live-iso. iso boots and runs when PAE box is checked for VBox kernel, iso fails to boot when PAE box is not checked. using boot paramater 'forcepae -- forcepae' i am still getting the 'pae missing' error message. i noticed that the boot parameters now end with '---' instead of '--' as was the case with 16.04 after 'quiet splash'. If this isn't a bug, what changed with the boot parameters?

Unable to run command [CODE] apport-collect 1755951 [/CODE] because system will not boot without a viable 'forcepae' boot option. Since ubuntu-mate is supporting 32-bit kernels, I hope that it will work for Banias Pentium-D CPU's with the forcepae boot option, since the CPU is quite capable of running PAE but does not advertise that fact due to a bug. It is ironic that PAE is required for 32-bit CPU's at all, since most of the surviving 32-bit CPU's are on a motherboard that cannot accept more than about 3Gb RAM anyway. For example, mine is maxed out at 2Gb RAM, making PAE moot for me (and I suspect almost everyone else too.) An alternative option, of course, would be to provide a nonPAE kernel.

This bug was filed for ubuntu-mate 18.04 beta. Ubuntu-MATE 18.04 release boots and runs on my Banias Pentium-M with the 'forcepae' boot option entered after the '---' (interrupt boot by pressing F6, press 'Escape' to type in boot options). Interestingly, Virtualbox still seems to need 'PAE/NX' checked for the DVD or iso to boot. I don't know if this is due to 18.04 or due to Virtualbox. I think we can call this bug squashed!
