It would be less intrusive to the kernel to supply a fixed do_brk() and replace the do_brk with a jump to your version.
I've written similar patch few days ago. The patch only modifies first instructions of do_brk() (it replaces them with jmp to function in LKM. It can be downloaded from http://wizard.ath.cx/fixbrk.tar.gz But beware, I wrote it in rush and it's pretty odly written :-) But it worked on my two servers (both were running 2.4.21 kernel with grsecurity patch).
