With a new i386 kernel build from sources this morning, I oberve:

bash-2.05b$ konqueror
sbrk: grow 4096 failed, error = 12
sbrk: grow 4096 failed, error = 12
sbrk: grow 4096 failed, error = 12
sbrk: grow 4096 failed, error = 12

A kernel from last night works fine.

These are the (relevant) patches transferred between the working and the 
failing kernel build.
