If you are running the installer in expert mode, and you are using
manual partitioning, you should have full control over this.
Here's how I invoke expert mode:
(1) Boot the install CD. At the main menu, press the down arrow key twice
to select "Help", then press Enter. You will be taken to a help menu.
There will be verbiage at the bottom ending with "boot:". This is a
"boot prompt", though that may not be obvious. At the boot prompt, type
expert
and press Enter. You can also add any kernel boot parameters that you
want to use during installation. For example,
expert clocksource=pit acpi=off notsc
I'm not necessarily recommending these boot parameters in your situation;
I'm just giving this as an example.
When you get to the "partition disks" step, select "manual partitioning".
This should give you full control. You create a partition by selecting
"free space" and pressing Enter. Of course, you can't create a partition
if you have used up all of the free space.
You can create a maximum of
four primary partitions. But once you create four primary partitions,
you can't create anything else. In order to create a logical partition,
you must have fewer than four primary partitions. You can create a
maximum of one extended partition, and I believe the extended partition
is implicitly created when you create the first logical drive.
I can't remember for sure. The /boot partition must be a primary partition
if you want to keep your original DOS/Windows-style master boot record
and install the boot loader in the boot sector of the /boot partition.
If you are going to install the boot loader in the master boot record,
then the /boot partition can be a logical drive.

I'm no expert on this, but with the installer's ability to resize
partitions when used in a rescue-like mode, I'm not sure that LVM is
really necessary in your situation. Others may disagree with me.
