Nice work, I think this will fix my problems :) I have some comments - not 
sure how many of them are sane.

I think the indent is wrong (mixed tabs + spaces) in ramoops_init. Tried to 
fix it, but my email client just made it worse :p

With this patch, ramoops_platform_data takes precedence over module 
parameters. Should it maybe be the other way? 

I think you can just statically allocate ramoops_platform_data, since it's 
only 2x(unsigned long)? You will use one more long in .data, but less in 
.text?

Not related to the patch: Should the printks end with "\n"? If i do 
printk(KERN_ERR "a"); printk(KERN_ERR "b"); I get two lines, but with 
printk(KERN_ERR "a"); printk("b"); they end up on the same line. So if another 
driver did printk without KERN_ after ramoops, they would end up on same line?
