Redhat linux and async io

Hi,

Oracle10g 10.2.0.1 (32 bit)
RHEL 4 update 3 (32 bit)

• I have installed the async io rpm's
  $ rpm -qa | grep aio
  libaio-0.3.102-1 libaio-devel-0.3.102-1

Questions:
1) How do i verify/check if the async io is enabled/loaded in RHEL kernel?
I solaris I used to
$ modinfo | grep kaio

142 1344ccb 4916 178 1 kaio (kernel Async I/O) 142 1344ccb 4916 178 1 kaio (kernel Async I/O for 32 bit com)

One of the Metalink docs says check
$ cat /proc/slabinfo | grep kio

2) How do I determine if the redlat linux installed is 32 or 64 bit version?
Is getconf LONG_BIT the only way to determine this or will uname -a show something specific.

Thanks for your help.
