Does linux cache partition table?

Greetings all.. a big thankyou to all those people who helped with
my last couple of questions, the solutions:

1) in /etc/conf/modules add 'alias parport_lowlevel parport_pc'
   and reboot (shouldn't need to, but.. just to get everything correct) 

2) mke2fs on /dev/hda7.. this actually worked later that day
   (see below).  

It seems that the kernal (or something, BIOS? motherboard?) caches the 
partition table.
 
It was decided to have 128Mb of swap, instead of 64Mb
So (not being familiar with fips,) /dev/hda6 (64Mb swap) and 
/dev/hda7 (rest, ext2) needed to be deleted by fdisk and recreated.

In single usermode, just to be safe: 

swapoff /dev/hda6
fdisk (delete and repartition)
mkswap /dev/hda6     creates 64Mb swap (why?)
<reboot>
swapoff /dev/hda6
mkswap /dev/hda6     creates 128Mb swap (all is well)
swapon -a
swapon -s            [just to check, all looks good]

Anyone know where the patition table is cached?
This explains my earlier problem, when I couldn't run mke2fs on the
newly created /dev/hda7.
