The Hayes HSP cards look like 16550AFN's, they just have much larger 
FIFO's than 16550's (16 bytes vs 1024 bytes).

This should work under Linux with no changes.

As for the Hayes V.FC+Fax 28800 running at 235kbps, don't be fooled. Ive 
tested these modems a fair bit. They get their 'extra' speed by using a 
larger BT-LZ Dictionary table. In reality, it seems best to set your port 
speed to 57600bps or 115kbps. 

They Hayes modems CAN acheive higher speeds than other V34/V42bis modems 
under special conditions (VERY repetitive data), but in real life, they 
perform much the same as any other 28.8kbps modem.

Having stated the above, I do beleive that the Hayes modems are built to 
a very high standard, good solid aluminium box, etc.
