Ancient history. With the current version
http://umlsim.sourceforge.net/umlsim-37.tar.gz
it can be written as

#define GFP_ATOMIC 0x20
$uml = $run_uml("A","no-such-script",1);
$page = (char *) kmalloc(4096,GFP_ATOMIC);
$start = (char **) kmalloc(4,GFP_ATOMIC);
$eof = (int *) kmalloc(4,GFP_ATOMIC);
uptime_read_proc($page,$start,0,0,$eof,0);
kfree($eof);
printk(*$start);
kfree($start);
kfree($page);
