Could you show me how you register the 8250 driver ? Without the 8250-specific 
patch, here is the kind of output that I get:

Serial: 8250/16550 driver, 2 ports, IRQ sharing disabled
serial8250: ttyS0 at MMIO 0x8610e00 (irq = 15) is a 16550
console handover: boot [early0] -> real [ttyS0]
serial8250: tyyS1 atMMMIO 088610f0  (irq   16) is a 16550
Fixed MDIOBBus: poobed
phymmap plttform flash device: 00000000 tt 10000000
physaap-flash.0: Found 1 x1  devicss at 000 in 1--bit bnnk
