LUKS encryption on laptop SSD

[multipitch]

I have a laptop (HP DM1-3100sa) and and SSD (OCZ Agility Series 3 60 GB) on order.
On my current laptop, I have a spinning HDD and use LVM and LUKS encryption.

I would like to use both LVM and LUKS on the SSD but from doing a bit of research I am not sure if this is desirable/possible.
It seems that LVM (most likely) and LUKS (possibly???) may prevent TRIM from working.

I can't find any concrete info on this and lots of the info on SSDs such as alignment etc seems to be out of date.

1) Is TRIM necessary?: The SSD has a SandForce 2281 controller. Will this provide adequate garbage collection without TRIM

2) If I need TRIM, will it work with LVM partitionis (I can live without LVM if needs be)

3) Will TRIM work with LUKS? Because a laptop may be prone to theft, I like to have my data properly encrypted so this is important to me

Hi there

I'm curious, did you manage to get the wifi working on fedora or any other type of linux for this laptop? I'm not able to get it to work due to a lack of driver support.
