It might depend on IOS release, but it's not platform-specific.

r3(config-if)#timeout absolute ?
<0-35790> Session lifetime (in minutes)

As we're also using this config command when applying a per-user
"Session-Timeout" Radius attribute, we seem to be limited to this value
(a bit more than 24 days).

Do you happen to know which ios version between the following 2 increased it?

12.1(11)
--------
3640(config-if)#timeout absolute ?
<0-35790> Session lifetime (in minutes)


12.2(15)T8
----------
5300(config-if)#timeout absolute ?
<0-71582787> Session lifetime (in minutes)

You're right, I just checked a 12.2 release. This was fixed by
CSCdw27408 in 12.2(7.5)T and others. Now you're indeed limited to 2^32-1
secs..
