USB Flash Drive Partitioning

[iandr0idos]

Hi!
I've searched Google for hours, but I can't find the answer anywhere.
I have an 8GB flash drive, and I want to install Chromium OS on it.
However, I would only need about 4GB of storage for Chromium OS. Allocating the other 4GB of space for Chromium OS seems like a waste to me.

I wanted to know if it was possible for me to partition the flash drive into two 4GB partitions, with one partition being the bootable Chromium OS and the other being a normal FAT32 file system.

If this is possible, can any of you kindly point me in the right direction as to how to accomplish this?

I run Ubuntu Linux 11.04 x86_64, but I can boot into my Windows 7 partition if needed.

Any help would be appreciated!
Thanks!

Sure, why not? I do this frequently. I install a live Linux on one partition, and use the other for data that I want to keep.
