I know it seems kind of weird that it is hanging even though you don't have 
any pc cards inserted. However, at the point when your init script echos 
'Loading PCMCIA Services: modules'  it is attempting to load the modules 
pcmcia_core.o and ds.o for your pcmcia _controller_.

I'm not very familiar with Sharp laptops. I have know idea what kind of 
pcmcia controller it has in it. Have you read through the pcmcia-howto?

This most probably sounds like an interrupt problem or an IO port problem. To 
quote from the pcmcia-howto:

3.3 Interrupt scan failures

Symptoms: 
 - The system locks up when the PCMCIA drivers are loaded, even with no cards 
    present.
 - The system log shows a successful host controller probe just before the    
    lock-up, but does not show interrupt probe results.

You can verify the latter statement by booting to a single mode (by-pass 
starting pcmcia) and look at /var/log/messages for info from the kernel about 
what happened when you tried to insert the pcmcia core modules. The problem 
could also be an IO port scan which is addressed in the same howto, section 
3.4 . At this point, I would suggest that you curl up with section 3.3 & 3.4 
of the pcmcia-howto. For the latest version go to 

http://pcmcia-cs.sourceforge.net/ftp/doc/PCMCIA-HOWTO.html

Hope you are able to find some options for action to take. Let me know if it 
works out -- or if you are still having problems ;-)
