> ioctl(5, RNDGETENTCNT, 0x1001000bd40)   = -1 EINVAL (Invalid argument)

Weird.
RNDGETENTCNT doesn't have returning EINVAL path.

Please run following program. I guess alpha, mips, sparc and ppc have 
different RNDGETENTCNT number against x86.

-----------
#include <linux/random.h>

main(){
  printf("%lx\n", RNDGETENTCNT);
}

This is the output:
 # ./a.out
 40045200

And here is my testing IRB session:

 # irb
 irb(main):001:0> File.open('/dev/urandom'){|f1|
 irb(main):002:1*         entropy_count = ""
 irb(main):003:1>         # get entropy count
 irb(main):004:1*         f1.ioctl(0x80045200, entropy_count)
 irb(main):005:1>       }
 Errno::EINVAL: Invalid argument - /dev/urandom
   from (irb):4:in `ioctl'
   from (irb):4:in `block in irb_binding'
   from (irb):1:in `open'
   from (irb):1
   from /usr/bin/irb:12:in `<main>'
 irb(main):006:0> File.open('/dev/urandom'){|f1|
 irb(main):007:1*         entropy_count = ""
