2.5.5-pre1, allow RAM disk to be build

Hi,

since 2.5.x (can't remember version correctly) the setup for RAM disk changed and I could not build it anymore into the kernel due to compilation errors. In the latest prepatch (2.5.5-pre1) this is still not fixed. I am using the following patch to fix this and it works from 2.5.x upto 2.5.5-pre1 without any problems.

please apply,

The real fix I think is to fix include/linux/blk.h setup.c uses it inside CONFIG_BLK_DEV_RAM, but blk.h only defines it with CONFIG_BLK_DEV_INITRD
