partitioning the PS3 HDD

Does anyone know if Sony is allowing for more partitioning options in a future update, or is there any way I can find out? I'm trying to install Linux on my 250GB HDD (you can replace the HDD), but the only partitioning options are 250/0, 240/10, and 10/240. I think that's kinda lame to only give you those options like everybody would only partition a 20GB. Will they have a system update to give your more options to split it more evenly, or is there a tricky way to do it w/o using the PS3 partitioner? Sorry if this is in the wrong forum, but I figured if Wii friend codes was a topic here, this would fit ok.
