Looks like something wrong with resource allocation. Here is how mine 
3132 looks:

siis0_at_pci0:4:0:0:       class=0x018000 card=0x31321095 chip=0x31321095 
rev=0x01 hdr=0x00
     vendor     = 'Silicon Image Inc (Was: CMD Technology Inc)'
     device     = 'PCI Express (1x) to 2 Port SATA300 (SiI 3132)'
     class      = mass storage
     bar   [10] = type Memory, range 64, base 0xfe9ffc00, size 128, enabled
     bar   [18] = type Memory, range 64, base 0xfe9f8000, size 16384, 
enabled
     bar   [20] = type I/O Port, range 32, base 0xbc00, size 128, enabled
     cap 01[54] = powerspec 2  supports D0 D1 D2 D3  current D0
     cap 05[5c] = MSI supports 1 message, 64 bit
     cap 10[70] = PCI-Express 1 legacy endpoint max data 128(1024) link

You've lost two memory areas somewhere. May be it is somehow related to 
it's ExpressCard nature, I don't know.

In theory card can be controlled via left third I/O area, but it is not 
supported now.
