I need 2 vlans and this just fails and fails. I can route from a port
assigned to the def vlan, but not from any port assigned to vlan 2

Have you created vlan 2 in the 'vlan database' in the CLI?
Do you see the proper ports assigned to vlan 2 in a 'show vlan'?

I assume you are going with the single port connecting the switch to
the router marked as a trunk port, rather than the port channel group
which isn't going to work with a router-on-a-stick 2600?

Which code rev of the 2924? Some of the older ones defaulted to ISL as
the default trunk type. Try making sure to do dot1q trunk type on your
trunk port.

interface FastEthernet0/0.1
encapsulation dot1Q 2
ip address 192.168.44.253 255.255.255.0
no cdp enable
!
interface FastEthernet0/0.2
encapsulation dot1Q 1 native
ip address 192.168.0.253 255.255.255.0
ip nat inside
no cdp enable

One thing I would strongly suggest with older gear especially is
staying away from VLAN 1 altogether. Cisco treats it special, and it
flip/flop'd alot on the router code. This way didn't work always.
Sometimes you needed

interface FastEthernet0/0
ip address 192.168.0.253 255.255.255.0

interface FastEthernet0/0.1
encapsulation dot1Q 2
ip address 192.168.44.253 255.255.255.0

to talk with the native vlan on the switch.

Once you move into multiple VLANs, and trunking them, then switch
everything away from VLAN 1 and the native vlan oddness that overtook
some hardware/software revs.

I am not sure how to set a interface or sub interface on a 2600 as a
trunk. All I see is a trunk-group command, Should I default that to
1 ?

I have tried dotq (specified it on the switch, because you were right,
it was isl.)

Right now, if the sub router interfaces are set to isl vlanid

and the switch trunk port is set to
switchport trunk encapsulation isl

I was able to get vlan working, well it's odd.

I have ports defined for vlan 2, the funny thing is, under isl mode I
can get a dhcp address just not on the 44 network. I get the native
vlan network. My dhcp server is set up for the second vlan range. Here
is my config:

At this point both work, however I do not get the correct address
range appilied to me. Maybe setting an ip address on the switches 0/11
interface will do it ?
I dunno I am kinda lost, I followed this post
http://www.velocityreviews.com/forums/t29496-router-on-a-stick.html

Yes this is a router on a stick setup
