ramdisk.gz and ramdisk address allocation in RAM

[KPal]

Hello.
I have an IXP425 dev. board with 64M RAM and 16M Flash.
Redboot doing:
1. zImage load to 0x1600000
2. ramdisk.gz - 0x0800000
3. go 0x1600000

My ramdisk size = 8192. And all works ok.
But i need to increase ramdisk to 16M (or to 12M).
But there is a problem: 0x1600000 - 0x0800000 = 0x0E00000 (14M).
ramdisk.gz ~ 2M,
what can be maximum size of uncompressed ramdisk?
I think, than in my situatition the sum of ramdisk and ramdisk.gz can't be > 14M?

Where will be uncompressed ramdisk allocated?
Can i change it position?

Thanks.

zImage - it's a Linux system with kernel and other.
ramdisk.gz - it's tour ram filesystem.
