We should also look at what drivers do depend on STANDALONE:
- some OSS drivers
- one DVB driver option (DVB_AV7110_FIRMWARE)
- ACPI_CUSTOM_DSDT

The OSS drivers are more or less RIP, so let's ignore them.

Is DVB_AV7110_FIRMWARE really still required?
ALL other drivers work without such an option.

ACPI_CUSTOM_DSDT seems to be the most interesting case.
It's anyway not usable for distribution kernels, and AFAIR the ACPI 
people prefer to get the kernel working with all original DSDTs
(which usually work with at least one other OS) than letting the people 
workaround the problem by using a custom DSDT.

It might therefore be possile simply getting rid of CONFIG_STANDALONE?

    Gentoo kernels are 42 times more popular than SUSE kernels among
    KLive users  (a service by SUSE contractor Andrea Arcangeli that
    gathers data about kernels from many users worldwide).

       There are three kinds of lies: Lies, Damn Lies, and Statistics.
