initrd support in 2.6 kernel

Hallo Guys!

I has initrd, that nice loaded by all 2.4 kernels.
But 2.6.9 kernel has some difference in loading initrd(as i discovered).
This warning produced by kernel on boot:

...SKIP...
Kernel command line: console=ttyS0,115200 root=/dev/ram0 
initrd=0x00800000,32M
...SKIP...
checking if image is initramfs...it isn't (ungzip failed); looks like an 
initrd
Freeing initrd memory: 32768K
... SKIP...
RAMDISK driver initialized: 16 RAM disks of 32768K size 1024 blocksize
...SKIP...
RAMDISK: Couldn't find valid RAM disk image starting at 0.
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(1,0)


Maybe troubles in kernel command line? But this command line work fine 
on 2.4 kernels.
