AFAIK only Win98 and Win95 systems dont have the supplicant. Win XP
has it built-in and for Win 2K you can download a patch from the microsoft
website. There are companies that sell supplicants (meetinghouse, funk etc)
and I think there are some WLAN card manufacturers whose client
has the supplicant built-in (Cisco ACU I think).

Colubris has a product which seems to support (atleast thats what I understand
from the diagram): http://www.colubris.com/en/products/public_access/CN3000
both 802.1x as well as webpage redirect & username-password, and might be
what you are looking for.

The Cisco AP allows you to have multiple SSIDs and map each one to a VLAN.
The security settings are different for each VLAN-SSID pair and while you 
can turn off WEP on one of the SSIDs and keep it on the other (even set
different WEP keys for each VLAN-SSID pair) I am not sure if you can do that 
with 802.1x (keep it off only on one SSID). Also, only one SSID will be 
broadcast, so you need some other way to tell users that there are multiple
SSIDs (the 'extra' SSIDs wont show up in the beacons).

There are also a number of new WLAN-Switch manufacturers who use thin APs, and
should presumably be able to support what you are looking for. On a related
note: its usually not a good idea to mix 802.1x and non-802.1x APs in the same 
network. The network is going to be only as strong as its weakest link! You 
can turn off 802.1x in all APs, and use a NAS to show a web-page and control
access to the network (thats what most hotspots today do) or just use 802.1x 
across your network.
