Only Linus determines what is put into the kernel.
And I am not the keyboard and console maintainer.
Perhaps I was, long ago.

Would I like
                blankinterval = arg;
? Perhaps. Easy and compact. Perhaps not. Apart from ioctl proliferation
and such concerns one might also worry about the possibility of several
consoles where only some must be blanked, etc. A single static variable
like blankinterval is no good. Having things in a struct also makes it
easier to manipulate VT state, to save and restore state.

I understand that you only need this for debugging.
In that case just doing s/10*60*HZ/0/ on the source seems easiest.
