Can I specify PBKDF2 rounds to use with LUKS/dm-crypt?

I have encrypted my root partition with dm-crypt/LUKS/cryptsetup on Ubuntu 12.04.

Since it uses PBKDF2:

Is it possible, during creation of the encrypted disk, to specify a custom amount of PBKDF2 iterations for key derivation?
Is it possible, after the encrypted disk has already been created, to modify the amount of PBKDF2 iterations for key derivation?

I'd like to make it a little harder to brute-force :)

I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD.

Does LUKS encryption affect TRIM? (SSD and linux)

I'm moving over to Linux when the new SSD arrives. SSD gives increased performance, so I thought that I could encrypt everything. But then I came to think about TRIM, and garbage collection on the drive. Will a LUKS encrypted drive affect the garbage collection system? (TRIM). >>> More
