    Where has the option to enable secure virtual memory gone in Lion?

    Additionally, I prefer the old method of being able to generate my own master password for file vault instead of using a system generated one.

    Advice and thoughts welcome...

    I would think that it is simply enabled by default, but you can check by going into the System Report :)apple:->About this Mac). It's listed as part of the System Software Overview.

    It is on by default now I think. I don't think it is possible to turn off via the GUI now.
    If you poked around the man page diskutil, corestorage section you probably can set your own.Not sure.

    Can't find it listed. Do you mean that it will be enabled by default if I enable full disk encryption? Not done that yet, if so...

    It probably works independent from full disk encryption. You have to click on "System Report..." to open up the detailed System Information view, and then choose "Software" from the left column. Then it should list whether Secure Virtual Memory is enabled or disabled.

    This makes a lot of sense. After spending a few hours reading the Arstechnica review of Lion (great, indepth read) it makes more sense.

    The disk encryption setup used sits ABOVE the file system. Virtual memory utilizes the file system and, I would assume, still passes through the encryption layer above to get there...

    Secure virtual memory is on by default now.
    Filevault 2 is not by default. See the man page for possible ways to set the recovery passcode yourself.
