How much memory can I save by configging a kernel?

[raindog308]

I'm running OpenBSD 5.0 in a KVM VPS. The VPS has 128MB of memory.

I'd like to squeeze as much RAM out of the kernel as possible to free memory. I've already turned off services I don't use.

I'm wondering if I'm wasting my time or if I would be able to actually recover a usable amount. If I'm likely to free 50K, I won't bother. If it might free 5MB, I'll give it a shot.

The VPS is only using one NIC, for example, has no audio, etc.
